July 16-20, 2001



Note: Dr. Tom Holtz and Dr. Michael Brett-Surman are answering dinosaur questions for ZoomDinosaurs in July, 2001 (as publicity for their new dinosaur book). We'll post your questions and send them Drs. Holtz and Brett-Surman. Many, many answers are in.

*Groan*... now we have Spinosaur fans...

Deinocheirus was a "super raptor"!

http://dsc.discovery.com/news/reu/20010526/hugedino.html

Check it out!

You dolt! The link is dead! Anyway the report is all wrong by the way.
from Damean, age ?, ?, ?, ?; July 20, 2001


There's no way Spinless-saurus could take on T.rex and win! If if even DARED to try, this is what will happen:

http://www.enchantedlearning.com/dinopictures/2001b/dinowarz2ht.jpg
from Damean, age ?, ?, ?, ?; July 20, 2001


Oh yes, it's almost certain that Deinocheirus is not a raptor.
from ?, age ?, ?, ?, ?; July 20, 2001


"The spinosaurids had jaws similar to a nile crocodiles(a freshwater crocodile), that had bite powerful enough to kill antelope and buffaloe. Even Tom Holtz said a spinosaurus could probably kill a Tyrannosaur(depends on luck)."

Well, actually crocdiles don't bite their prey to death, they simple hold them under and drown them in the case of large prey. Also, save for shape, Spinosaur skulls are very different from crocdile skulls. They're lighter built, have large holes in them, and the bones are thinner. The only reason they seem to have the same shape is, I am guessing, convergent evolution to catch fish and not large prey. And thus we see Spinosaurs lacking the adaptations to bite as hard as his aquatic counterparts. Of course, crocdiles also start twisting and turning their entire bodies whenever they get a bite on large prey to cause extra damage, something a Spinosaur could not do. Not to mention they have extremely strong and thick necks to handle the head, adaptations that Spinosaurus did not have. I'm not saying Spinosaurus was not a predator of big prey, but he, despite his size would have been less formidible for the other non-fishing dinosaur predators of his time. Of course, I respect Tom Holtz's opinion, but I don't think every paleontologist really spends alot of time dissecting dino-fights (not unless they want to keep their job), so I'd say what he said was a generalization. The odds are certainyl quite heavily in T.rex's favour.

" Hey Sauron it's likely Spinosaurus had an 8ft. skull because truly,the spinosaurus was 60 feet tall.in the movie they chopped it down to about 45 feet,and still it was six feet taller than Tyranosaurus.I think it could grab a hold of the neck and snap it."

Tall or long? I tink you are saying long. Wait a minute...wouldn't a 60 feet tall Spinosaurus be almost be as tall as a Brachiosaur? I dunno...if you are talking about the JP3 monsters, than anything is possible, but in real life, this is not the case! Spinosaurus was probably about 20 feet all. And he can't really grab hold of T.rex's neck for four reasons:1) His hands had no opposible thumbs and could only flex in, making it impossible for him to "grab" and "snap" a neck. 2)His hands are actually quite low slung under his body and are quite out of the way for this kind of action 3)In real life he's actually SHORTER than a Tyrannosaurus it'll be a challange to use his arms on Tyrannosaurus' neck. 4)T.rex's neck was too stonrg and thickly built to be snapped easily by Spinosaurus, even if he had the extremely unlikley grip. Infact, T.rex has the strongest neck of all carnivorous dinosaurs ever. His neck can even take other T.rex bites!

"IT's easy to see how t-rex lost the fight.The rex legs were stubby which were better for long walks,rather than running,which suggests that it was most likely a scavenger,not a hunter.Spinosaurus though,his legs were for running which were probably more powerful and gave it more leverage for a better and stronger attack.Plus it was six feet taller than rex in the movie,which made it even harder for rex to get leverage on his bite to the spinosaurus's neck,plus the weaker legs which were not that powerful for pumping into the bite."

Actually this is a factual error. Tyrannosaurus has the best legs for running among all dinosaur predators (incuding the raptors, but they weren't built for running anyway). Tyrannosaurus' legs resemble, measurement for measurement, those of ostrich dinosaurs. Spinosaurus on the other hand, had legs that were short for a predatory dinosaur its size. Shoulder to shoulder (including the 6 foot sail), Tyrannosaurus was about the same height as Spinosaurus, and without the sail, you'll see Spinosaurus actually looks kinda silly with his short legs:) Tyrannosaurus was almost certianly better built for speed than Spinosaurus. And it's more likely he was also a more formidible hunter.

"I think it's likely that raptors could talk,since they seem so much like birds.Birds communicate to keep the flock together,and if raptors did travel in flocks they needed to communicate."

It depends on what you mean by "talk". I suppose it's extremely likely that most dinosaurs could communicate by sound, but certainly not to the level shown in JP3.

"But please, there are no dinosaur inaccuracies in JP3, because there are no dinosaurs in JP3! Listen to Dr. Grant- these are monsters, not real dinosaurs. They can look however they wanted them to look."

Sadly, Dr Horner insists thet are scientifically accucrate.

Annoyingly, if they call the JP3 raptor as Utahraptor, then they should calling it a Velociraptor!
from Honkie Tong, age 17, ?, ?, ?; July 20, 2001


did you know im a little kid and im an expert at dinosaurs ask me any questions
Example:(If you ask me wat is a Ornithosuchus i will say: Ornithosuchus is an archosaur (early ruling reptile) Ornithosuchus was once thought to be a dinosaur of it's skeleton and size. it was around 13 ft. 13 feet is an average size for a meat eater in the triassic period. thats why it was once thought to be a dinosuar.

from julian, age 9, ?, ?, ?; July 20, 2001


Brad, for your list of JP stuff don't forget the cute little chickadee in J.P./// ! Oh and there is a (japaneese) commercial with goijirasaurus in it (the japaneese verion of the JP3 replacxes raptors with goijirasaurus. (not footage but names) ...
from Russlander, age imortal, The Lair, N/A, Russland; July 20, 2001


The movie "Ceratosaurus" had forwadly-directed eyes, a thick conical horn on the nose, and no 'horns' above the eyes. The real Ceratosaurus had eyes on the side of its head, a more delicate nasal crest, and 'horns' above the eyes.

But please, there are no dinosaur inaccuracies in JP3, because there are no dinosaurs in JP3! Listen to Dr. Grant- these are monsters, not real dinosaurs. They can look however they wanted them to look.
from Brad, age 14, Woodville, ON, Canada; July 20, 2001


Oops nevermind about Tom Holtz...there he is hahaha. I thought i saw him in a book or something that's why!
from ?, age ?, ?, ?, ?; July 20, 2001


Oh yeah, who is Tom Holtz? I think I've heard of him...not quite sure though. And J, leg length has nothing to do with bite power.
from ?, age ?, ?, ?, ?; July 20, 2001


T-Rex's legs are not "stubby" as you would put it. They are actually rather long in proportion to its body. In fact, spinosaurus was the one with "stubby" legs and limited mobility. Some think it may have even walked on all fours!
from ?, age ?, ?, ?, ?; July 20, 2001


J, other spinosaur supporters, show me something that states that spinosaurus is 60 feet long and posessed an 8 foot skull (other than JP3 sites).

According to my sources, the destroyed spinosaur was approximately 15m (49.5 feet)long and about 4 tonnes (4.1 tons) in life. There is no mention of an eight foot skull (in fact, only the front half of the lower jaw was ever found).
from ?, age ?, ?, ?, ?; July 20, 2001


Hey Brad, how was the ceratosaurus inaccurate. The ceratosaurus was 20-25 ft. and had a horn on it's nose. That's how it looked in the movie.
from T-man, age 17, ?, ?, ?; July 20, 2001


In Dino Warz mabey you should let some other dinos win besides Trex (maybe a DILOPHOSAURS)
from andrew d, age 10, 12345, 67890, lalalalalalalalalalalalalalala; July 20, 2001


The velociraptors probably should have been called Deinonychus, since they were size of the movie raptors, and they were Montana. Velociraptors were from Mongolia.
from T-man, age 17, ?, ?, ?; July 20, 2001


Yea, they say that raptors did have feathers, but they don't know how many. They say most theropods have had feathers when they were at one point in their like, probably at a young age.
from T-rex, age 17, ?, ?, ?; July 20, 2001


The spinosaurids had jaws similar to a nile crocodiles(a freshwater crocodile), that had bite powerful enough to kill antelope and buffaloe. Even Tom Holtz said a spinosaurus could probably kill a Tyrannosaur(depends on luck).

Check it out!
from AB, age 16, Pahrump, NV, ?, ?; July 20, 2001


Recent specimens show that Tyranosaurus was larger (taller, longer and heavier) than Spinosaurus. The Spino in JP3 was WAY overblown and built far too heavily. I real life that inital T.Rex bite would've meant instant death to the Spino, or any other creature for that manner. T.Rex was far stronger and had a much stronger bite. It's hard to imagine the waek jaw of Spinosaurus doing much damage to the heavily built T.Rex. At all.
from Hey J, age ?, ?, ?, ?; July 20, 2001


I do think raptors had ways of communicating, chimps and whales both make distress calls to others. And whales seem to have a language to communicate in. And chimps use a primitive sign language to talk to each other. The velociraptors in movie probably should be deinonychus, because who they resemble the most. And when Dr. Alan Grant made a distress call, it did confuse the raptors because they wouldn't any other animal would make that sound. And velociraptors are not as smart as movie makes them, maybe other dromeosaurs, but not the veloci.
from T-man, age 17, ?, ?, ?; July 20, 2001


Are raptors really supposed to have feathers?
from Katie V., age 14, Tabernacle, NJ, U.S.A.; July 20, 2001


A comment on the Rex/Spino fight.....Spinosaurus had the arms,being able to take hold of the head and snap it even more easily,T-Rex only had the jaw.And if you read one of my earlier comments on big rex,he had smaller legs which gave less leverage in the bite,and he was six feet shorter.
from J, age 16, Atlanta, Georgia, America; July 20, 2001


I think that it is quite possible when the group is surrounded and he makes the distress call that they will become confused.If they are really are smart as they think,they would consider all else inferior to them,including humans.They would assume that grant could not make that noise,seeing as he is a different species and "inferior" to them.PLUS there were a lot of them,making them look like a pack.It is also possible that they thought they were other raptors,because they stole the eggs.they may have thought "Why would anopther species take our eggs?" and when he made the call,maybe they thought they were calling the rest of the pack for help so they dicded not to make trouble and just take the eggs and scram.
from J, age 16, Atlanta, Georgia, America; July 20, 2001

from J, age 16, Atlanta, Georgia, America; July 20, 2001


On the inaccuricies sections,the shape of the velociraptor skull seems perfectly logical,along with the spindly feathers on the head.Velociraptors were active dinosaurs,which brings into play the warm-blooded theory.If you recall in JP1 in the beguinning they are examining the V-raptor skeleton,and it was like a bird.birda are warm blooded and the V-raptor skull shape is more beakish,like a bird,because remember,they have evolved since the first movie eight years ago.
from J, age 16, Atlanta, Gerogia, America; July 20, 2001


"Hmmmm... looks like to me if you scale that creature to 10 foot arms you have an animal AT LEAST 30 feet tall. 40 wouldn't be too far-fetched."

I never said 30-40 feet was out of the question, but 60 feet definitely is...
from Chandler, age ?, ?, ?, ?; July 20, 2001


Hey Sauron it's likely Spinosaurus had an 8ft. skull because truly,the spinosaurus was 60 feet tall.in the movie they chopped it down to about 45 feet,and still it was six feet taller than Tyranosaurus.I think it could grab a hold of the neck and snap it.
from J, age 16, Atlanta, Georgia, America; July 20, 2001


Blood on the plane was from the guy, not the spino ...
from T-man, age ?, ?, ?, ?; July 20, 2001


Spinosaurus did have a 8 ft. skull, kinda like a skull but wider. And why would that be impossible from how big they got.
from T-man, age ?, ?, ?, ?; July 20, 2001


Yup, JP3 is inaccurate. But I think the film was better than The Lost World. Though not as good as, Jurassic Park.
from DW, age ?, ?, ?, ?; July 20, 2001


"was it a Carnotaurus or a Ceratosaurus?"

Neither! If it was supposed to be a Ceratosaurus, it is a very inaccurate one. I think its just a theme park monster, as Grant said.
from Brad, age 14, Woodville, ON, Canada; July 20, 2001


Actually I confirm Honkie's statement that JP3 bombed in my country. The critics tore it apart and the audience showed indifference to the movie, claiming it wasn't exactly realistic in terms of dinosaurs and that the storyline was nothing special. And yes, the Spinosaurus is viewed more of a cheap trick to boost ratings and to make JP3 something "new" it didn't work. Oh no!

Moral of the story: Don't count on calling your dinosaurs "realistic" to soon after Waking With Dinosaurs.
from Leonard, age 14, ?, ?, ?; July 20, 2001


Actually Justin, I don't think that picture of Deinocheirus you claim to be more accucrate looks more like Suchomimus...hey wait...it is a Suchomimus!!! What's this? I don't think its likely Deinocheirus looked like a Suchomimus, or was even closely related to a Spinosaur at all...
from Leonard, age 14, ?, ?, ?; July 20, 2001


"It would probably break one of his arms and he would have hard time getting up."

Hmm...while T.rex arms are extremely stong, scientists have discovered that they were not strong enough to actually help the animal off the ground. T.rex probably got off the ground like any other bird we see today. They don't need no arms! What about the arms? The mating theory and showing obscene signs to intimidate other dinosaurs (suggested by Lillian) seem possible!
from Leonard, age 14, ?, ?, ?; July 20, 2001


"They say dinos like spino and suchimimis probably had bites like crocodiles. Now that would be a pretty a strong bite. Not as strong as T-rex's, or enough to kill Rex with one bite. But a spino and giganoto could stand a chance against a T-rex. But T-rex does have better chance cause of it's bite."

Honkie rasied a very good question when he said that D.
Actually, Spinosaurus and Suchimimis actually had skulls that are more similar to the narrow-snouted freshwater crocidiles than the slab-sided broad jawed ones. However, Spinosaur skulls in general have alot more holes and the bones in general are very much thinner, in some cases, almost paper thin in the case of Suchimimis. They certainly were no slouches in biting, but their bite force was certainly quite that below of other carnivores of their time, including crocidiles. Giganotosaurus like Allosaurus didn't have to much of a bite force too, they seem to rely on lacerating and weakening their prey with repeated bites with their lightly built skulls to kill them while Tyrannosaurus seemed to rely on a single, devestating, bite that caused as much damage as possible. Is this why the rip-and-bleed Allosaurs had vanished up in the north and given way to the smash-mouth tatics of the Tyrannosaurids?

Hmm...actually the act of falling itself would be extremely bad for any 6-ton animal, regardless of its speed. I think T.rex got around this problem like any other large animal by simply not falling at all at speed! Not to mention with a large counterbalanging tail, it was probably more well balanced than any ostrich or running biped we see today. I guess the reason why we see falling as such a common affair is that as the top-heavy, extremely unstable bipedial animals we are, we are more prone to falling and thus see it in that way in other bipeds. Even if he fell, I suppose T.rex would have an instinctive way of falling (like cats) to reduce or neglate the damage done, such as whipping his tail to regain some balance or to shift a foot forward to stumble and bring the fall to rest on his heavily-built pubic bone. If he fell in a belly-splat (like if he tripped over a log or something) it would be a bad thing though, but I think he was too careful and balanced to do such a thing. I certainly think it's rather likely he had a way of dealing with falling, given that he was more built for speed than any other genera of large carnivorous dinosaur.

Honkie raised a very good point when he said that D.mirificus lived in different times as Spinosaurus...I think the D.mirificus vs. Spinosaurus theory is all but dead...(in fact, I think it was a scam in the first place)

Also, if memory serves, the other species of Deinocheirus is a much smaller animal than the original animal. This is an extremely dubius specimen and I'm not sure is it's a Deinocheirid at all. But no specimens or fragments certainly have ever been retrieved from Africa and from the time where Spinosaurus lived, so I think this should be enough to kill off the Deinocheirus ate Spino theory...

It's amazing what a little research can do.
from Leonard, age 14, ?, ?, ?; July 20, 2001


Innaccuracies in JP3 (warning, contains some spoilers):

1. The Pteranodons had teeth!

2. The Pteranodons flapped too much. As I understand it, the pterosaurs lacked the kind of musculature that would enable them to continually flap like that.

3. I doubt that a Pteranodon could carry off a human which was probably heavier than itself.

4. (This is an old arguement): Velociraptors aren't that large.

5. The velociraptors don't even look like velociraptors. The head appears more like Dromaeosaurus. I'm not sure, but I think the hand-orientation is wrong as well. Not enough feathers too (my assumption is based upon recent discoveries of a mongolian dromaeosaur very similar to velociraptor, which sported a vast array of feathers).

6. It's extremely doubtful that Velociraptors would "talk."

7. In the end, where the group is surrounded, Grant manages to execute a PERFECT imitation of a raptor "distress call" through a REPLICA of a "raptor resonance chamber." The raptors look around as though confused, then confiscate their eggs, and take off into the jungle. Doesn't this seem odd to anyone else? COME ON!!! The raptors would've traced the noise DIRECTLY IN FRONT OF THEM!!! Geez.

8. The way the spinosaur dispatched the t-rex (broke its neck) and then managed to THROW it is unlikely.

9. Spinosaurus is too bulky. According to every source I could find, they all state that the original WW2 specimen was long, but very gracile and light weight.

9. The spinosaur would've at least been noticably injured, if not killed, by colliding with a plane (blood seemed to spray the entire aircraft).

10. Spinosaurus's skull was too large, as was the rest of it now that I think about it. The length was about right though I think. EIGHT FOOT SKULL??? No where in predatory dinosaurs is there a skull that large. Only skulls that large are marine predators and ceratopsians.
from Robber Eggbert, age ?, ?, ?, ?; July 19, 2001


In every published text that I could find on dinosaurs, they categorize Deinocheirus as either an ornithomimid, or (less commonly) a therizinosaur.
from Sauron, age ?, ?, ?, ?; July 19, 2001


The animal that appeared in the scene with the Spinosaur droppings is the Ceratosaurus. I think the movie could have done without its appearance, as it did nothing at all of importance; other than showing up. The same for the ankylosaurs.
from Sauron, age ?, ?, ?, ?; July 19, 2001


Dilophosaurus (((((((((((((((((RULES!)))))))))))))))))

Tyranosuars fans just are not right!

VOTE FOR THE DILOPHOSAURUS!!!!!!!!!!!!!!
from andrew d, age 10, 1234, 5678, The US; July 19, 2001


I think it looked like a Ceratosaurus.
from Megan H., age 14, ?, ?, ?; July 19, 2001


Besides the raptors and pteranodons, what's inaccurate about the movie?
from T-man, age ?, ?, ?, ?; July 19, 2001


And it was a good idea to another carnosaur besides the T-rex(though it probably should not have died). After a while, you get tired of T-rex.
from T-man, age ?, ?, ?, ?; July 19, 2001


They say dinos like spino and suchimimis probably had bites like crocodiles. Now that would be a pretty a strong bite. Not as strong as T-rex's, or enough to kill Rex with one bite. But a spino and giganoto could stand a chance against a T-rex. But T-rex does have better chance cause of it's bite.
from T-man, age ?, ?, ?, ?; July 19, 2001


It was a Ceratosaurus, carnotaurs don't have horns on their nose. They have them above their eyes.
from T-man, age ?, ?, ?, ?; July 19, 2001


According to Dr. Holtz and Dr. Brennar, The spinosaurus probably weighed up to 8 tons. I guess it wasn't as light people thought. And the T-rex only got up to 7 tons. And giganotosaurus did get up to 8 tons. And just because had a more powerful bite, doesn't mean he was stronger that the other carnosaurs. I doubt a spinosaur could kill a T-rex that fast, but one bite from a T-rex will not kill a big dinosaur( like triceratops or spinosaurus). A T-rex would have to bite it 2 or 3 times kill it. Just because T-rex could take a 500-pound chunk, doesnt mean he could do it instantly. He probably did that when the animal was dead or pinned. And If a did fall at 20 mph, I doubt it would kill, but it would hurt it. It would probably break one of his arms and he would have hard time getting up.
from T-man, age ?, ?, ?, ?; July 19, 2001


i saw JP3. it was a great movie. i have one question. In
the scene when they were searching the Spinosaur's droppings
for the cell phone, wat was that dinosaur that came up on them?
was it a Carnotaurus or a Ceratosaurus?

Actually JB, Deinocheirus in all probability looked something like this

from Justin, age ?, ?, ?, ?; July 19, 2001


The most famous exhibit is a fossil of Velociraptor mongoliensis fighting with Protoceratops andrewsii. There is also a pair of "hands" belonging to an unknown dinosaur (named Deinocheirus mirificus), probably a carnivore twice the size of Tyrannosaurus rex.

"I suggest anyone wondering what _Deinocheirus_ could have looked like go to Luis Rey's site: http://www.ndirect.co.uk/~luisrey "

Hmmmm... looks like to me if you scale that creature to 10 foot arms you have an animal AT LEAST 30 feet tall. 40 wouldn't be too far-fetched.
from JB, age ?, ?, ?, ?; July 19, 2001


Honkie Tong, isn't that just the Dinosauricon's profile of Deinocheirus? I was just there, and there's a possible second species of Deinocheirus! Just a specimen number though, no description. :(
from Brad, age 14, Woodville, ON, Canada; July 19, 2001


Thanks for letting me know about the Luis Rey update. Why would Deinocheirus have a yellow tongue?
from Brad, age 14, Woodville, ON, Canada; July 19, 2001


I found the movie JP3 entertaining, despite the fact that the T-rex died. Although the Spinosaurus may not be highly appreciated, I found the change in enemies good, because I find the T-rex to be the only predator that is known to young kids in the world. They should learn the names of some others that are just as interesting. It was also nice to be able to get a closer glimpse at the Pterodactyls in the movie, for in the others, they were only small bird-like flying creatures in the sky. The raptors also gained a new look, as is apparent in the one's head, with the small feathers. Some of the facts may not have been accurate, but this is a movie, not something that should be taken seriously. And is it true that Steven Speilberg has an idea for a 4th one already? I have heard this somewhere but I am not positive of the source. Thanks.

You're right Scott, JP3 did have a lame ending but I think the rest of the movie, despite the raptor and Spinosaur inaccuracies, was good.

Okay, next time I want to post my opions I'll go to somewhere less critical. Sorry on my mistakes! Thank you Katie for the support and sorry Brad, you're right, I had mistaken info. Honkie Tong, cool it, no wonder you and Sean don't get along!

I suggest anyone wondering what _Deinocheirus_ could have looked like go to Luis Rey's site: http://www.ndirect.co.uk/~luisrey
Go the the "what's new" page. There's also an excellent _Spinosaurus_ there.
Luis is a great artist and I think he is often overlooked.

"I find that a 7.5 ton theropod would only need about 81 kg/day of meat to live). "

This is pretty cool, this means that a Tyrannosaurus would have needed to kill a gross mass of 3-4 triceratops a year. Of course, this is not counting the fact that T.rex would not finish off all of a carcass so he would have to kill or scavenge more. I estimate his stomach would have been able to hold quite a lot of meat (300 kilos?) to keep him going for some time before he needs to kick butt or eat some dead animal again, much to the relief of the other dinosaurs around. Of course, if he did hunt in a social group, a triceratops should be enough to fill up about 10 or more Tyrannosaurus for about a week, assuming each gorged on a hundred kilos of meat a day. They would get a little fat.
from Leonard, age 14, ?, ?, ?; July 19, 2001


Dandebunked! (No it's not german!)

The science behind Dan's Deinocheirus theory!

"One swipe from Deinocheirus and his massive claws would take out T.Rex, Spino or whatever else it crossed. "

Let me see, 30 centimeter claws are impressive indeed, but they certianly don't do as much damage as being speared by a charging triceratops or being clubbed by an Ankylosaur or being whipped by a sauropod. If T.rex and Giganotosaurus (I'm not sure about Spino) could take that, I suspect a swipe from Deinocheirus might not take them out immediately and Deinocheirus is better running his butt away...but at 15 tons (as you say) he's not going to do much running.

"Everyone is jealous and biased against Deinocheirus"

Jealous against a dinosaur know from two arms? Hardly. Besides I prefer not to take any frim stand on this animal till is better known, but let me test your points for null intergity, somthing I have discovered it is seriously lacking. In fact, by insisting and demanding Deinocheirus is a raptor, you seem to be the one who is baised!

"At LEAST 25 feet tall, possibly up to maximum of 40 (Glut) "

Hmm, he would have been tall, if he was an ostrich-mimic, due to their stance...but 40 feet seems to be an enitrely excessive estimate. Actually, I did some scaling of a raptor diagram to give it two meter arms and found that it was still surprisingly small! Even smaller than T.rex!

"Arms are Raptor-like (Glut) "

Actually, the arms have certain distinct differences with the arms of raptors: They were too wide, the hand could not curve in fully as much, and the claws and digits were considerably more curved and long than you will find for a raptor. All in all, the arms are more similar to that to Ornithomimosauria (despite certain differences too) that that of Deinonychosauria.

"Spine fragments are Raptor-like (Glut) "

Erm, actually raptor spines are coelurosaur-like like any other coelurosaur, so the best guess you can hazard is that Deinocheirus was a coelurosaur, not a raptor.

"Tracks attributed to Deinocheirus with 15 foot walking stride (Morrison) "

This is really strange. Firstly we do not know how Deinocheirus feet looked like, and secondly, finding gigantic, three foot long, two-toed footprints should have caused a gigantic upheaval in the paleo world, I find nary a blip. In fact, the single T.rex footprint is better known. My guess is, the morrision tracks have been misidentified or do not exist at all.

"Teeth are Raptor-like (Glut) "

Nope, I've researched on this and have discovered that Deinocheirus might have had some teeth (holotype)! But the best idea of them was that they were small, conical and with little recurvature, certainly quite different from raptor teeth. I also don't buy the teeth theory, there is virtually no documentation I have seen of it, despite researching it! Hee...hee and not to mention Spinosaurus and Deinocheirus were seperated by a sea at that time! Deinocheirus lived in Laurasia while Spinosaurus was isloated in Gondwana! There is also a posibility of a time difference; Deinocheirus was early Maastrichtian while Spinosaurus lived in the Albian to early Cenomanian! How could they meet? If "Glut" really said that, he is most likely wrong!

"Deinocheirus-like teeth found in remains of Spinosarus and Sauropods (Glut) "

A misleading statement that makes it look very apparent and widespread. Evidence or any on this part must be extremely vague and hard to intrepret. The species is hardly known (and I seriously doubt the existence of dental evidence, even the excellent dinosauricon didn't mention it) and bite marks and teeth if made by it will be very, very difficult, if not impossible to determine with accuracy.
And the rest of the problems with this point are about the same as the point above.

"If it walks like a duck, quacks like a duck, looks like a duck......"

Hmm...but in this case, we don't know how it walked, we don't know how it looked and we certainly don't know how it sounded. If we have had this much fossil evidence from a chicken, we might mistake it for a duck too!

Who is this Glut guy anyway? Sound like a bad and poorly trained paleontologist to say all these things, but then again...he could have been set up here...

Giganatocheirus mirificus is a good name!

And Brad is not a T.rex fan, I'd like to clear that up for him.
from Honkie Tong, age 17, ?, ?, ?; July 19, 2001


Saw JP3 yesterday. I must say the story was very lame. And am I crazy or were the effects better in JP1 and 2? The hang gliding scene with the pterosaurs looked really weak. The petrosaurs themselves looked really good though. Best animated animal of the movie. The Spinosaur was SO lame. It's almost funny to think that thing killed the T.Rex. The ending is very weak. The marines- OH JOY.
from Scott, age 16, ?, ?, ?; July 19, 2001


"So Deinocheirus was some kind of a giant duck, they sould call it Gigaanato!"

If Deinocheirus was duck-like, Gigaanato has the same meaning as Anatotitan. :( How about Giganatocheirus- not every duck has claws like that! :)

And just a little note- it's possible to like Deinocheirus without thinking of it as a super-predator! Personally, I find the idea of a tree-dwelling sloth-theropod very fascinating! I think I'll paint a picture of it. :)
from Brad, age 14, Woodville, ON, Canada; July 18, 2001


"At LEAST 25 feet tall, possibly up to maximum of 40 (Glut)"

People thinking that Deinocheirus is a Velociraptor keep saying they got their information from Glut- could you please be more specific? What is the title and date of this work you are refferring to?

"Tracks attributed to Deinocheirus with 15 foot walking stride (Morrison)"

Sounds kind of suspicious. How reliably can you attribute tracks to something whose feet are unknown?
from Brad, age 14, Woodville, ON, Canada; July 18, 2001


Deinocheirus rules and you all won'tadmit it! One swipe from Deinocheirus and his massive claws would take out T.Rex, Spino or whatever else it crossed. Everyone is jealous and biased against Deinocheirus. Too many half truths here from the T.Rex people.

Dear all

I have just joined DinoTalk and I thought I would let you all know about an up and coming webcast my museum is launching next week.

>From the 23 to 27 July, my museum will be hosting a fossil-dig webcast from the central Australian desert. The webcast has been specially designed for students aged 6 to 18 and will allow them to link to palaeontologists uncovering the remains of Megafauna. Megafauna were huge animals - giant Kangaroos, giant birds and giant crocodiles etc - that roamed Australia for millions of years. Fossilised bones of these animals have been found all over Australia, however there is a very rich site in the middle of the Simpson Desert, in a place called Alcoota.

Next week Australian Museums On Line will be setting up a satellite link to Alcoota, which will allow people from all around the world to email questions to paleontologist from the Museum and Gallery of the Northern Territory, who are currently working on the site. So feel free to log on and have a look at the site now, because aside from the webcast, you will also find a host of educational games and resources about Australia's unique megafauna.

_Deinocheirus_ WAS NOT 50 feet long...ornithomimes (and therizinosaurs and oviraptorosaurs, too) had very long arms/claws compared to actual body length.
from Chandler, age ?, ?, ?, ?; July 18, 2001


"I've never called Deinocheirus a therizinosaur, I said it was an oviraptorosaur."

I'm sorry, that is what you said. Ooops...
from Chandler, age ?, ?, ?, ?; July 18, 2001


Answers from Brad:

"If you yourself say Glut classifies it as a theropod, why do you still call it a oviraptorosaur??"

First, oviraptorosaurs are theropods! I'm not certain that deinocheirs are oviraptorosaurs, it was just a suggestion.

"If you say the claws are called "raptorial", but that does not make it a velociraptorine, what are they from then? A triceratops? A chicken?"

A Deinocheirus. Haven't we already established that?

"You said:
"It came from anatomical comparisons by A.K. Rozhdestvensky, in 1970. If mammalian sloths were unkown, I'd find them improbable too."

So you are relying on 31 year old information? Hmm. I'd like to see a 15 ton animal hang upside down from a tree! You're 14? And have a 31 year old book?"

I don't have Rozhdestvensky's paper, but Glut gives a summary of it in his 1997 book. I don't see how anatomical comparisons can become outdated. Why do you insist Deinocheirus weighed 15 tons?

"You said:
"I doubt it. Teeth cannot be referred to Deinocheirus, because the holotype consists only of the forelimbs and shoulders. And there's the fact they they lived at different times/continents"

You are using 30 year old quotes, so maybe you are using centuries old text as well. You see, back then there was no "Africa" , no "South America" etc. , it was all grouped togther in a massive
land mass. Crazy, huh?"

In the early Mesozoic, yes. But by the time Spinosaurus and Deinocheirus evolved, the continents had separated and developed unique types of dinosaurs. African dinosaurs and Asian dinosaurs of the Late Cretaceous would not interact. And there is the fact that they lived at different stages of the Late Cretaceous...

"Also, fyi, more than arms and shoulders of Deinocheirus were found. They also found teeth, vertebre fragements and rib fragments. If you research things a little you'll see this. Just b/c you know of the famous picture showing the arms on display doesn't mean that's all that was found, you know. The teeth of Deinocheirus match almost exactly the records of the teeth found imbeded in the Spinosaur from the 1915 Spinosaur dig. And yes, he was right in saying that this was
destroyed during WW2. They were destoyed during the bombing campaign."

There's a differene between "Known material" and "Holotype material". You're right about the ribs and vertebrae being found, but I still don't believe you about the teeth.

"All the info. is out there if you just take the time to look. It's better and more productive than spreading hearsay and falsehoods."

Yeah, but big unproductive debates are kind of fun. :) Seriously, I do research.

"I think all of you T.Rex crazies can't stand to admit there were other formible theos out there, Esp. a 50 footer with 10 foot arms with foot long claws that would slice up T.Rex in about 2 seconds!"

I'm not a T. rex crazy, I'm actually more of a Deinocheirus crazy!
from Brad, age 14, Woodville, ON, Canada; July 18, 2001


"The teeth of Deinocheirus match almost exactly the records of the teeth found imbeded in the Spinosaur from the 1915 Spinosaur dig. And yes, he was right in saying that this was destroyed during WW2. "

Finding teeth in Spinosaursu dosen't mean Deinocheirus killed Spinosaurus (If that's even true, I have scoured the net for Deinocheirus teeth in Spinosaurus and turned up nothing). The scant knowledge of Deinocheirus anatomy suggests to me that Deinocheirus would have most likely been scavenging instead of hunting. Of course though, the morphlogy of Deinocheirus hands suggests they were slashing tools instead of grappeling tools. Defense? Mabye. Not the first of theropoda to evolve size as a defense.
from Damean, age ?, ?, ?, ?; July 18, 2001


"If you say the claws are called "raptorial", but that does not make it a velociraptorine, what are they from then? A triceratops? A chicken? "

Actually, the troodon sickle claws are "raptorial" too, but they are not velociraptorine. But I doubt it would have been a raptor, even paleontologists think so. Thomas Holtz, a paleontologist who specializes in studying meat eating dinosaurs like the raptors also believes so:

What in the heck was Deinocheirus? It had to be a meat-eater. What did it hunt? Big sauropods? That thing is scary!
from Paul, age 12, ?, ?, ?; July 17, 2001

TOM: Deinocheirus had huge scary arms, but it probably wasn't that frightening a dinosaur! The details of the arms are nearly identical to those of smaller ostrich-mimics like Struthiomimus, Ornithomimus, and Gallimimus. So Deinocheirus was probably just an ostrich-mimic dinosaur the size of a T. rex. The diet of ostrich-mimics (technically called ornithomimosaurs) isn't certain, but most paleontologists think that they were omnivorous: eating plants, eggs, and small animals. In the case of Deinocherius, though, an adult protoceratopsian or pachycephalosaur would count as a "small animal". It probably did not hunt big sauropods, but it might have hunted the babies of the sauropods that lived in its environment (Opisthocoelicaudia and Nemegtosaurus).
from Damean, age ?, ?, ?, ?; July 18, 2001


Spinosaurus? More like Spineless-saurus! That thing could never beat a T-Rex! And 40 foot tall predators won't be doing much predating anyway, most of the things would be much faster and more agile than it.
from Damean, age ?, ?, ?, ?; July 18, 2001


There's nothing to admit, T.rex is still the most formidible predator around. Why? Becasue he had no time to be anything less.

Tyrannosaurus rules!

from ?, age ?, ?, ?, ?; July 18, 2001


I don't think Allosaurus hunted fully grown adult sauropods unless they were really weak or sick. They would have attacked the younger sauropods when they were still small and within reach. Like Ankylosaurus, once the animal got to a certian size, it was virtually invulnerable to attack. Given that, I think its unlikely that Allosaurus would have needed much jumping, given that it did not hunt the adults. A two ton animal jumping up 20 feet is by the laws of physics, unsensible unless you have a jet pack. I don't think Allosaurus femurs can resist or put up with 6 giganewtons of force required to jump 20 feet at all. Besides, hanging onto the back of a sauropod for dear life while trying to kill it is hardly a good tatic.
from Honkie Tong, age 16, ?, ?, ?; July 18, 2001


Personally, I feel its extremely unlikely that Deinocheirus was a Dromaeosaur. Looking at Deinocheirus arms strikes me as more from a therizinosaur dinosaur, or somethign in that league. I think the reason the arms were "raptorial" was probably due to convergent evolution or plain coincidence, the same design for a different job. But I don't think its really sensible to make such assumpitions about an animal known only from the arms, but I think its quite unlikely it would have been a Dromaeosaur.

"Diplodocus and Apatosaurus had long whip like tails that could probably split a human in half. "

It is almost certian that they would have used their tails for defense, but whipping a predator will likely cause massive damage to it and I think it would have been resorted to as a last ditch measure. True enough, the tails of sauropods show stress injuries from moving the tail, but none indicating an actual-contact-on-contact hit with a predator. Wipping a tailtip around at supersonic speed and making a racket would have probably detered the predator.

"Allosaur could keep going even if it suffered from broken body parts. Many skeletons found have broken ribs, arms, cracked thigh bones, broken knees, broked toes, cracked jaws, and broken fingers. Most of those injuries acquired through hunting."

Actually, the adverage Tyrannosaurus skeleton shows more serious injuries that didn't stop the animal. Multiple compound fratures of the leg that somehow healed, broken necks, penetration wounds to the brain cavity, fractured tail veterbre, ribs and so on and so forth. Tyrannosaurus skeletons show more evidence of serious injuries, but oddly, the its common for a Tyrannosaur to survive a long history of them. Tyrannosaurus fossils are certainly showed they took a lot more pounding and survived while they were alive.

"Think about a Tyrannosaur. They specialized in hunting hadrosaurs, Torosaurs, and Triceratops. Tyrannosaur wouldn't know what to do if it came up face to face with a herbivore that big. It wasn't devloped enough to take the stress of the whip like tails or spiked tails of Stegosaurs. If placed in the Jurassic era, it would die in a matter of days, most likely killed by a pack of Allosaurs/Ceratosaurs or by having its neck broken by getting hit with the tail of an Apatosaurus or Diplodocus."

Actually, latest discoveries indicate Tyrannosaurus most probably hunted in a pack too, and I doubt even a pack of Allosaurus would want to take on a single Tyrannosaurus (There are easier prey around). And I'm afraid to tell you that Tyrannosaurus' neck was far heavier built than Allosaurus, as was for the rest of his body. He would have been able to take a far lot more hits and survive. In fact, Tyrannosaurus was so tough, we have actually found evidence in one individual that it at some point in its life, sustained a serious neck fracture that it not only survived, but recovered most of its ability to hunt. If you ask me, Tyrannosaurus could take a great deal more stress from pounding, battering, crushing and smashing than Allosaurus or any carnivore for that matter.

"My dear Lillian, T.Rex could not run faster than a Utahraptor. Yes, most likely it could beat a Utahraptor at a long distance race, but in a sprint...NO! "

Well, if the raptors were built for great, short range acceleration and extreme agility. For that, their legs have extremely short lower bones. Tyrannosaurus on the other hand, had legs that closely resembled those of the ostrich-mimics, or ostrichs in general. Raptors actually have leg designs closer to that of humans than of ostrichs! Flat out, a Tyrannosaur is expected to outrun a raptor easily, and last longer too. And yes, its extremely unlikely he would fall, given his adaptations for speed.

"Iguanodons are thought able to run fourty miles and hour, around the speed of a greyhound or horse."

I don't think so, Iguanodon most probably had a top speed faster than that of a raptor, but it's unlikely a 5 ton animal can reach 40 miles per hour. 20-30 is a better estimate, certainly faster than that of a Utharaptor though. Once again, its extremely likely that an Iguanodon could outrun a raptor going flat-out, raptors don't chase their prey for distance, they weren't designed for that.

About the septic bite issue, I don't think Giganotosaurus or the Allosaurus in general had a more septic bite than modern day predators like the lion or such. Tyrannosaurus though... is a different matter...

from Brad, age 14, Woodville, ON, Canada; July 17, 2001


"Brad suggested a while back that perhaps it was a giant therizinosaur, and that's possible too (ornithomime-therizinosaur group rather than a oviraptorosaur-therizinosaur group?)."

I've never called Deinocheirus a therizinosaur, I said it was an oviraptorosaur.

"Chandler, you're spreading unsubstaniated theories. Deinocheirus was indeed possibly a form of raptor as Donald F. Glut wrote about in his paper about this topic. A raptor scaled up to include those massive arms would've been around 40 feet tall."

What paper? He called it Theropoda incertae sedis in Dinosaurs: The Encyclopedia. The claws are called "raptorial", but that does not make it a Velociraptorine!

"I don't know where that sloth theory comes from. It's hard to imagine a 15 ton creature using it's foot long killing claws to hang from a tree. That makes no sense."

It came from anatomical comparisons by A.K. Rozhdestvensky, in 1970. If mammalian sloths were unkown, I'd find them improbable too.

"I don't know what that Spinosarus hunting thing is about. Glut said that Deinocheirus teeth were found in the Spinosarus remains that were destroyed during world war II but that doesn't mean that it was it's main prey. It probably hunted the mega-sized sauropods."

No offence to anyone these are my own opinions but I don't think T-Rex fell too often, it must have adapted to running and maintaining its balance. T-Rex could have gotton damage from something else, after all, it prey was huge too!
from Katie V., age 14, Tabernacle, NJ, U.S.A.; July 17, 2001


Megan H., great job on your comments, they were very interesting! I also think T-Rex wasn't a scavenger he/she was too big (for big prey) although I think it would have eaten already dead food (hey, who wouldn't pass up free food?).
from Katie V., age 14, Tabernacle, NJ, U.S.A.; July 17, 2001


Urgh! Yes Allosaurus can jump! Look at Allosaurus Fragilis, who weighed around a ton to two tons at the biggest! If you are thinking that Fragilis weighed over two tons you are wrong! You're thinking of Allosaurus Maximilus who weighed much more and was heavily built. I believe that they (Fragilis) could jump quite a disance vertically, but maybe not as far horizontally. Diplodocus is a 95 foot sauropod. Its neck going to be pretty far off the ground (think about it)! Also, Diplodocus and Caramasaurus both had a sharp toe spike on their feet and if they happened to rear up, they would put themselves in a defense position with those claws able to keep a predator away and their necks would be out of reach. So what would you do? Go for the back and ribs! Yes, the back wasn't fifty feet off the ground but it was a reasonable distance! You still would have to jump to get up there.

I know I will get a lot of crud for this but here it goes.

I believe the young of the Fragilis could glide for a couple of yards. Please don't start dissing this right away! Some specialists on small theropods and dromeosaurs believe if small and light enough, they could glide. Like most people, I believe dinosaurs had feathers. The young of A.Fragilis could have used feathers on their arms to glide for a distance but as they reached around sixty pounds, they lost that ability.

Honkie Tong, I doubt if a A.Fragilis or A.Maximilus jumped up twenty feet and fell, they would die of shattered bones and burst organs. Look at the prey again. They hunted sauropods, Stegosaurs, and Gargoyleosaurs. Diplodocus and Apatosaurus had long whip like tails that could probably split a human in half. A young one could do that to you. Allosaurs had to be strong enough to take those blows and keep going. If hit in the neck or ankle, it would be death but if hit in the ribs, the Allosaur could keep going even if it suffered from broken body parts. Many skeletons found have broken ribs, arms, cracked thigh bones, broken knees, broked toes, cracked jaws, and broken fingers. Most of those injuries acquired through hunting.

Think about a Tyrannosaur. They specialized in hunting hadrosaurs, Torosaurs, and Triceratops. Tyrannosaur wouldn't know what to do if it came up face to face with a herbivore that big. It wasn't devloped enough to take the stress of the whip like tails or spiked tails of Stegosaurs. If placed in the Jurassic era, it would die in a matter of days, most likely killed by a pack of Allosaurs/Ceratosaurs or by having its neck broken by getting hit with the tail of an Apatosaurus or Diplodocus.
from Megan H., age 14, ?, ?, ?; July 17, 2001


My dear Lillian, T.Rex could not run faster than a Utahraptor. Yes, most likely it could beat a Utahraptor at a long distance race, but in a sprint...NO!

Look at the build of the Utahraptor or any other dromeosaur relative. Long, thin legs, straight rudder like tail, thin neck that could be carried straight out or in a tight S shape, and a deep chest cavity. Do those charcteristics sound familar? Look at how a cheetah or a close relative, the ostrich, was built. The ostrich can run up to fourty miles an hour while the cheetah tops seventy. The Utahraptor's prey also was quick. Iguanodons are thought able to run fourty miles and hour, around the speed of a greyhound or horse. Utahraptors lived at the same time as Struthiomimus cousins (not sure of the exact species) and those could probably run around fifty miles an hour by looking at the spaces of the footprints and the ankle bones. Also the hips of the Utahraptors were built so the raptor had a long, out streaching gait. The gate meant to gain distance while maintaing a speed around sixty miles an hour.
from Megan H., age 14, ?, ?, ?; July 17, 2001


If you read my previous comment, I added onto it!

Hey Jeff, I believe the Nannotyrannus was NOT a juvenile Tryrannosaur. There could be many reasons the skull was only attactched to the vertebrae by cartilage or other grisle like flesh. Maybe it lived in a wooded area where it hunted small prey. A flexible skull would be useful to dark between branches to get small lizards, bugs, hatchling or small juveniles of other dinosaurs, or small mammals. Honkie Tong, you're right. At the most, a Pteradon would weigh a hundred pounds, like Ornithocierus who had a forty-foot wingspan. But even with a wingspan like that, the wing membrane is thinner than a post-card. Good for gliding and hovering, not good to help it pick up things. Pteradon most likely was a fisher or scavenger. Below is some other stuff I'd like to clear up.

The people who said the Tyrannosaur is exclusively a scavenger are wrong. Scavengers are not built like that, look at it. The Tyrannosaur has long ankle bones built for speed, much like an ostrich. The head is heavy with a strong lower mandible for taking shock from wiggling prey. Look at its prey, Triceratops and types of hadrosaurs were huge, some reaching almost as big as the Tyrannosaur. Also people should not always refer to the Tryrannosaur as only a male enity because the largest specimens found were females. Females most likely were larger because they had to protect their young from Dromeosaurs and small mammals who'd gladly raid a nest.

Another point I would like to hit is the Velociraptor size. Because of the Jurassic Park movies, many people think that the Velociraptor is a large six to eight foot tall beast. Wrong! The Velociraptor averages two to three feet high and up to seventy pounds. Yes, they did hunt larger prey like the Zuniceratops or again, small hadrosaurs. But they grew no bigger than that. The raptors in the movies were most likely Utahraptors considering the size. Something about Utahraptors now. Contary to what most people think, scientists have come up with theories of how the Utahraptors used their hands to kill instead of the large ten inch claws on their feet. I support this theory.

In Jurassic Park III, it shows the Spinosaur killing a Tyrannosaur. I think this is wrong because the reports on the Spinosaur show that it had a weak jaw and more suited for catching fish than catching a Tyrannosaur. I'm not saying I don't like the movie, but the chance of a Spinosaur killing a Tyrannosaur is very highly unlikely.

I like Allosaurus, they were effiecent predators who most likely hunted in packs like wolves to help them bring down large prey like Diplodocus, Apatosaurus, Juvenile Brachiosaurus, Caramasaurus, and Stegosaurus. They would have had competition from Ceratosaurus who was a predator reaching about the same size. What most people don't know is that there are two main Allosaurs; Allosaurus Fragilis and Allosaurus Maximilus. Fragilis weighed around one ton to two tons and was 10 to 13 meters in length (from what I have researched) and Maximilus was two to five tons and up to 16 meters in length, the size of a small Tyrannosaur. It is my theory that Allosaur Fragilis, because of its smaller size, would travel in packs with almost twenty members and would live in forested regions or in mountainous regions. Instead of having the larger sauropods as a food source like Maximilus most likely did, they would have gone for smaller prey like Caramasaurus, Gargoyleosaurus, Stegosaurus, Dryosaurus, Othneilia, juvenile Diplodocus, Ornitholestes, Rhamphorhynchus (most likely hunted by the hatchlings or juveniles of the pack), Elaphrosaurus, and sometimes Ceratosaurus. Like the Tyrannosaurs, female Allosaurs would be much heavier and would be the dominant one in a mated pair. In a Fragilis pair, there probably be a dominant pair consisting of the largest female and male. Those are my theories and feel free to comment on them.
from Megan H., age 14, ?, ?, ?; July 17, 2001


T.rex had a more septic bite than giganotosaurus?! Is that all the evidence you have? You started insulting me, before i started insulting you! I'm realy tired of arguing with you trouble makers. Why can't we discuss discuss anything like adults?! (This is ridiculous!!) I'm not backing down! There's no need to talk to people who are unwilling to admit, that t.rex is not the king of dinosaurs. If t.rex means this much to you, i'll stop questioning it. Good grief.
from Sean.S the critic (IT STINKS!), age 13, ?, ?, U.S.A; July 17, 2001


_Deinocheirus_ is usually regarded as a giant ornithomimosaur (not a velociraptorine), and it wasn't as huge as you said, Saul (only allosaur-sized)! Brad suggested a while back that perhaps it was a giant therizinosaur, and that's possible too (ornithomime-therizinosaur group rather than a oviraptorosaur-therizinosaur group?).

Why Do You T-Rex Fans Have To Keep Voting For T-Rex When You Already Win The Vote?
from euoplacephulas, age 8, Alta, CA, USA; July 17, 2001


Saying:
"if t.rex ran over (20-30 mph.) it would fall and die."

Is like saying:
"if Sean posts more than 2 posts, the rest of them will be plain rubbish"

Claming that T.rex would automatically fall down and die when he runs about 20 mph is entire nonsense. I doubt he fell much at all. In fact, running birds rarely fall and if they do, they get wounds on their feet smilar to that Big Al got. Conclusion: Allosaurus was so clumsly that he fell alot of the time, T.rex was so good that he could run faster than Allosaurus and not fall! Amazing!

"" pound for pound, allosauriods were the best."

It's almst certain that Allosaurids were one of the weakest large carnivores in terms of meaness, pound for pound. A Tyrannosaurus or raptor of the same weight will always prevail over the Allosaurid. (You can't even spell Allsaurid!)"

I thought "allosauriods" was a misspelling of Allosauroidea- basically the same thing, but including the sinraptors.
from Brad, age 14, Woodville, ON, Canada; July 17, 2001


Deinocheirus is probably not Velociraptor, and its deadliness is difficult to determine. Deinocheirus is often considered a relative of the ornithomimids, but this is not certain. Scaled up from an ornithomimid, Deinoceirus is 25 feet tall, not 40. The claws are similar to those of sloths.
from Brad, age 14, Woodville, ON, Canada; July 17, 2001


"This giganatosarus/spinosarus vs. T.Rex debate makes me laugh. HA HA. Everyone knows that T.Rex had over double the biting pressure of those weak wannabes."

That is so wrong James...he had over TEN times the biting pressure! Giganotosaurus at best would have managed 1000-2000 newtons. T.rex bit to 15,000-20,000 newtons of force! Cool eh? And good job Leonard, you just about deflated Sean's crazed arguments.

Of course T.rex is kick butt, he came from the same dinosaur family as the raptors. And we know that anything coelurosaur is really cool an advanced and makes anything allosaur look lame. For example, they have troodons! They have raptors! They even have Deinocheirus! And they have the king of dinosaurs and the best among them! Tyrannosaurus rex!

I so agree with this song man!

Tyrannosaurus rules!

WE ARE THE CHAMPIONS!

This song also goes out to coelurosaurs like the troodons and the raptors for making such a great dinosaur called Tyrannosaurus.
from Lillian T., age ?, ?, ?, ?; July 17, 2001


This is getting biased... If Allosaurus could bring down a Diplodocus in packs, Allosaurus in a large pack MAY be able to bring down T. Rex. The T. Rex may or may not be able to turn in enough time to bring them all down. Either way, Big Al could do some pretty big damage before it goes down.
from Samuel C., age ?, ?, ?, ?; July 17, 2001


Deinocheirus would beat them all! He was the most deadly donosaur. He was a mega-sized velociraptor with 10 foot long arms and 12 inch claws on each hand. He would've been about 40 feet tall and 60 feet long. I believe Deinocheirus hunted and ate Spinosaurus as his main food. He could have killed Supersaurus and Ultrasaurus with ease if they were still around.

This giganatosarus/spinosarus vs. T.Rex debate makes me laugh. HA HA. Everyone knows that T.Rex had over double the biting pressure of those weak wannabes. He was built much tougher, was much stronger, was much faster and could do more damage in one bite than those other posers could do in several. And allosaurs? Give me a break. They probably got their butts kicked by the early mammals that were around T.Rex was supreme evolution on display. The most perfectly adapted killing machine ever, more so than sharks, more so than cats, and certianly more so than dopey looking fish eating overgrown alligators like the spinosaurs.
from James M., age 14, Lexington, MA, USA; July 16, 2001


Why is Sean using so many names? Split personality?

"That sounds like the testimony of a crazed t.rex fan! How do you know giganotosaurus didn't have an adaptation for using bacteria as a weapon?! Experts say this is how acrocanthosaurus killed it's prey!"

Animals like Tyrannosaurus have special adaptations for storing baterial, like the cubular serrations to trap meat within the teeth. Despite showing considerable diversity as a genera, Allosauriae do not have such serrations. Their teeth had delta serrations for slicing meat and nothing else. In fact, the theory arose about T.rex having septic bites when they realized in tests that model T.rex teeth trap alot more meat than Allosauriae teeth, also, the teeth of T.rex did not slice meat cleanly, but rather shredded it, making it extremely good for the profiliation of bateria. I suppose dental hygine would not have been good for Giganotosaurus, but I doubt he would have used this method as he lacked the proper adaptations. Unliek Tyrannosaurus, I doubt he could deliever anything to overwhelm the standard issue immune system of his prey animals. Tyrannosaurus certainly had the adaptations to be far, far more septic.

"If this holds true,it would probably work for the rest of the bunch."

Nope, it's like saying all dinosaurs had feathers. This is probably a method specialized for Tyrannosaurus. (This properity has not been noted in other Tyrannosaurids)

"By the way Damian,i like you'r points. But you'r still ignoring the power of giganotosaurus, and exaggerating tyannosaurus.(yes i was talking Damian) Dashing head on to a giganotosaurus, is like sticking you'r hand in a blender!"

Unless Giganotosaurus could dislocate his neck and spin it like a propeller blade, it would be like sticking your hand in a blender. Anyway, Gigantosaurus had a very lightly built skull and can't risk damaging it doing anything mtoe dangerous liek ramming. He wasn't buitl for that. Any T.rex would easily break any part of Giganotosaurus skull with a bite. Not good to have your face bitten off.

"I'm no Jack Horner, but i think if t.rex ran over (20-30 mph.) it would fall and die."

This is simple. Tyrannosaurus was so well balanced, it rarely, if never fell down while goign at speed. It's like saying falcons will die if they flew into a wall at 50 miles per hour, so they limited their speed to below that (we know that's not true, falcons exceed 150 miles per hour in a dive). You can't place restrictiosn based on "ifs". I doubt Tyrannosaurus did too much falling at all. He certainly could move fast, much faster than Giganotosaurus.

"The king, and all the kings men could never put him back together again!"

Of course, humans didn't exist then.

" pound for pound, allosauriods were the best."

It's almst certain that Allosaurids were one of the weakest large carnivores in terms of meaness, pound for pound. A Tyrannosaurus or raptor of the same weight will always prevail over the Allosaurid. (You can't even spell Allsaurid!)

"once again,t.rex fans falter in the face of allosaurus fans! note:Sin will take you farther than you want go.Sin will keep you longer than you want to stay. Sin will cost you more than you'r willing to pay."

"Incedible Hulk to a dinosaur two tons heavier than itself! The giganotosaurus got up to 8 tons, and the T-rex got up to 6 tons."

T-rex is something atomic ant, super-strong for its size. Giganotosaurus weight advantage is only gonna serve to slow it down. T-rex is gonna run circles around Giganotosaurus, and worse, bite far harder and with deadiler effect than Giggy...Giggy sissy is going down! Heck, T-rex could simply run straight into Giganotosaurus at 40kph. If its a head-on-collision, Giganotosaurus will fracture its skull or neck. If its side on, Giganotosaurus will fracture alot of ribs. In any case, T-rex's stoutly built configuration will win the day. T-rex is built like a friggin' tank compaired to Giganotosaurus!

It's very likely a plane crashing into Spinosaurus will kill it. Spinosaurus seems to be armoured in the movie, what's up? Did Horner say its scales were made of some indestructible alloy that can even resist T-rex bites?
from JP3 is going downnnnnnnnnnnnnn, age ?, ?, ?, ?; July 16, 2001


Ha! Ha! Ha! Now I know why Allosaurus fragilis went extinct! They were trying to fly! Towards the end of the Jurassic, many a herbivore must have stared in amazement at the sight of a 3-ton animal sailing 20 feet into the air before gracelessly slamming into the ground and smashing just about every bone in its body, ending up a wreck of pulped meat and bone. The Allosauriae south didn't get wind of this trend and survived. Up north, in the land of America is covered in millions of craters with smashed Allosaurs within, and the Coelurosaurs decide to take over, spawning the dromies and the Tyrannosaurs...as a final insult to the dead Allosaurus who tried to fly, the Coelurosaurs also produce the aves, which finally achieve full dinosaurian flight. In fact, everytime you see a bird, you are actually looking at the modern day survivors of the dromies, troodons and Tyrannosaurus, and every time they call, they mock the long dead Allosaurus who tried to! fly...

The reason why WWD is dull and boring is because its realistic? Hello? Dinos don't go around picking fights at the drop of a hat.

Yes, 94 minutes is kinda short for a JP movie. But it was going downhill all the way. Goodness, I expect a Spinosaurus to be hurt when a Helicopter crashes into it!
from ?, age ?, ?, ?, ?; July 16, 2001


Spolier Alert!

Spinosaurus won the battle. But strangely, there were scenes where T.rex did bite Spino in the neck. And we know that if T.rex bit anything in the neck, it's one dead dino! I mean, come on, a Tyrannosaurus with a bite force capable of splitting hip bones of 9-ton dinos with a bite did hardly any damage when it bit the spino in the neck???? What is this? Is the spino wearing chobbham lamated armour around its neck? Also, according to JP3, Spinosaurus killed rex by breaking his neck with its jaw. This is also extremely strange (not considering the fact that the Spinosaurus even survived a neck-bite by rex) for T.rex had a very heavily built neck that could take alot of pounding. And Spinosaurus certainly didn't have the dental equipment and the strength to bite down so hard. Heck, we have evidence that other T.rex bit other T.rex on the neck, and even at such forces, T.rex survived the fractured neck and went on to kill again. You're telling me a Spinosaurus can so easily break ! a T.rex neck like it was a twig???

The match is rigged.

And a more accucrate figure for Giganotosaurus was about 7.5 tons. 8 tons is a little overweight. Of course, Tyrannosaurus still had a great advantage in speed and strength. And if he could take bone-crushing bites from other T.rex, he'll handle what Giganotosaurus can throw at him, but I think Giganotosaurus will not be able to get even beyond the second bite by T.rex.

I was also watching the WWD scenes. The Allosaurus didn't jump onto the Sauropod. It did a short leap to bite it. It didn't jump onto it!
from Damean, age ?, ?, ?, ?; July 16, 2001


it is not likely that Carcharadontosaurus or Giganatosaurus had VERY potent bacteria in its mouth. The reason scientists believe that T.Rex had a poisonous bite is that Komodo Dragons from Indonesia have teeth which are very similar to Tyrannosaurs, amd Komodo Dragons have poisonous bites due to the rotting meat trapped in their teeth. The victim dies of blood poisoning within 48 hours. Carchardontosaurus had teeth that were (obviously) shaped like sharks, meant to shear off huge chunks of meat. Giganatosaurus had standard Allosaurid teeth(I think so), to which the closest comparison I can make is to lions.
from DW, age ?, ?, ?, ?; July 16, 2001


Speaking of walking with dinosaurs,remember that seen where a young diplodocus is jumped by an allosaurus? Although it was computer animation, i'm sure allosaurus was able to make these jumps. Don't insult me, just look at it. It was desighned to throw itself at it's prey!(that should be obvious) All you t.rex fans do, is give t.rex the win on a silver platter! That's like saying Harry Potter and all his friends went strait to hell for practicing witchcraft! (not that Harry Potter is a real person anyway.) T.rex was tough.(but so was giganotosaurus!) You can tell by looking at giganotosaurus, that in the flesh it was an awsome predator. Even if Teddy rex could win,giganotosaurus was far from a push over. As the cretaceous period went on, the giganotosaurus and carcharodontosaurus met most of the same types of dinosaurs t.rex knew as defferent species.(such as chasmosaurus) So they had contend with more than just sauropods. Both t.rex and giganotosaurus had awful bacteria in their mouths. The legs of allosaurus may have not been as strong as t.rex, but they're strong enough! Note: if you make fun of my favorite dinosaur,(like Honkie Tong did)i'll make fun of you'r dinosaur in ways you can't imagine!
