Dino Talk: A Dinosaur Forum Late May 2000

Late May 2000

Hi, Robert. I'll admit, you're probably smarter than me. I support D. torosus evolving to T. rex, I've read about the transitional form too. I'm not so sure about the Stegoceras to Pachycephalosaurus, mainly because I'm not sure about the exact age of each genus. Maybe. The coelophysid feather, I highly doubt! Sorry, but Dilophosaurus is not form Montana, its from Arizona. Montana doesn't have any Early Jurassic fossils, Dilopho's age, its Late Jurassic, Early Cretaceous, and Late Cretaceous. Deinonychus is an eight-foot-long, Montana theropod that is more advanced than Dilophosaurus, and could have left the feather. If you can give more evidence for Dilopho and some evidence against Deinony, I'll consider it. I've never seen Customizing the Velociraptor. If it is a web page, give me a link, please! Biggest, Baddest etc. sounds vaguely familiar, but I'm not sure where, when or how. Lastly, 'avilain' is not a term I've ever used before. W! hat is the difference between Avilae and Maniraptora? Is Maniraptora a combination of Avilae + Dromaeosauridae? Are Sinosauropteryx, Caudipteryx and Protarchaeopteryx avilains? Is Archaeopteryx avilain? Help me. I link Troodon to Ornithomimidae in Bullatosauria, which goes with Tyrannosauridae to make Arctometarsalia. Is this right? Help me with coelurosaurs, Robert!
from Brad, age 13, Woodville, ON, Canada; May 31, 2000

Brad,I forgot to mention the feather from Montana possibly belonging to an 8 ft. tall Ceolophysid...the only match is Dilophosaurus (see Costomizing a Velociraptor).Read Dinosaurs the biggest,baddest etc. for G.carolinii being a scalvenger. Bambiraptor was the smartest avilain Dinosaur (the birds and most bird-like dinosaurs),not the smartest non-avilian,which is Troodon.Bambiraptor may be a avian avilain(because its so smart).
from Robert S., age 9, Lawrenceville, G.A., U.S.A.; May 31, 2000

Brad, in answer to the May 2 entry you made about the test to find out how old bones are, it's called Carbon-14 dating. This is a bit out of date, but my messages almost always are.
from Neil M., age 10, Toronto, Ontario, ?; May 30, 2000

The half-life of carbon-14 is 5,568 years; this is too short a half-life to date dinosaurs. C-14 dating is useful for dating items up to about 50,000 - 60,000 years ago (useful for dating organiams like Neanderthal man and ice age animals). Uranium-235 (which has a half-life of about 700 million years) is used for older sediment, like those from the Mesozoic Era. JC

D.torosus(a.k.a. Daspletosaurus) evolved into T.rex. Transitional fossils have been found. In this case it took 5 million years. Each time it grew larger,and made more adaptions,until it was an 18 foot T.rex. Same for Stegoceras to Pachycephalosaurus.
from Robert S., age 9, Lawrenceville, G.A., U.S.A.; May 30, 2000

Gee Brad, you really know a lot about dinosaurs! Did you see Disney's new movie " Dinosaur" yet? I like the part when that big meteor hits the Earth. Anyway, since you know so much about dinosaurs, once you're done with my first qustion, I've goy another one. Could scientists really clone dinosaurs or any other prehestoric creatures?
from Phillip S., age 10, Sterling, Illinois, United States; May 28, 2000

Thank you, Phillip. I admit that I don't know what dinosaurs really looked like. I saw Dinosaur the day after it opened. I though the meteor shower looked more like a big fireworks show than an actualt natural disaster. And didn't nearly all of the lemurs die in that scene? Every other scene was good. I especially liked the opening sequence since it was probably the most true to science, showed a lot of dinosaurs, and had a cool effect where it felt like the seat was moving (when the pterosaur flew). I actually own an entire book that is entirely about the possibility of cloning dinosaurs, so I find it difficult to sum it up in a paragraph. I would say maybe, with a lot of luck.
from Brad, age 13, Woodville, ON, Canada; May 29, 2000

I like the skeleton of a trex
from daniel, age 6, widnes, ?, england; May 28, 2000

I really like dinosaurs! I like them because it's cool to think big wild animals, who hunted, ate, swam, breathed, lived, and died on the same ground we walk on every day. I wish that in a swamp or in a jungle somewhere they were still alive. But, I've been wondering, what did dinosaurs really look like?
from Phillip S., age 10, Sterling, Illinois, United States; May 27, 2000

What is the name of the large carnivore with the spikes on its head from the movie Dinosaurs? Was it bigger than t-rex?
from pierson c, vancouver, WA, usa; May 27, 2000

Hi, Pierson. The large predatory form in Disney's Dinosaur is the Carnotaurus. It was smaller than T. rex, but infinately cooler looking. Carnotaurs were 25-30 feet long, while rexes were about 40 feet.
from Brad, age 13, Woodville, ON, Canada; May 27, 2000

How do you put the dinosaurs togather
from anthony, age 6, gettysborg, penn, usa; May 27, 2000

Hi, Anthony. If you are assembling a dinosaur of your own, then look for instructions on the box or included on a piece of paper. If you are wondering how palaeontologists put together dinosaurs, there are a few ways they work. They have to identify the bones first, and figure out which body part they were. This is done by comparing them to the bones of living animals. If they are lucky, a palaeontologist will find a skeleton that is already in good enough shape to put together. But there are usually missing parts. If they bones are from a known species, then they use more complete specimens of the same species to make casts and fill in the gaps. If its an unknown species, then they look at related species and have a sculptor make the bones they way the would likely have been.
from Brad, age 13, Woodville, ON, Canada; May 27, 2000

Dinosaurs will live on at MCdonalds! After the Disney Dinosaur promotion (aprox. June 13), McDonalds will distibute three Beanie Baby dinosaurs. They will not be part of the happy meals, but will be sold separetely. There will be Happy Meal Beanie Babies too, but they will be ladybugs and fish and stuff. The three Beanie dinosaurs will be a Stegosaurus, a Tyrannosaurus, and a 'Brontosaurus'. They will sell out fast, since the larger Beanie Baby versions of this trio is in the $1000 range. See if you can catch them!
from Brad, age 13, Woodville, ON, Canada; May 25, 2000

Ooh! I missed dinosaurs in and out on national geographic, I feel really upset that I missed it to since its really interesting.. and was about the some big dinosaur feast when a herd of diplodocus got stuck in the mud and a lot of allosaurus attacked them, can't remember the location tho..anyways it was very interesting or was it on Jurassica.. Ooh! and I saw sue the large T-Rex..
from Sharon, age 23, Manchester, Dunno, England; May 24, 2000

Does Allosaurus have 3 claws or 4 claws?
from Raveena L, age 8, Cedar Grove, N J, U.S.A; May 24, 2000

Hi, Raveena. Allosaurus had three fingers on each forefoot, and four toes on each hindfoot. I am pretty sure all of its digits had claws. Relatives of Allosaurus are Yangchuanosaurus, Carcharodontosaurus, and Giganotosaurus.
from Brad, age 13, Woodville, ON, Canada; May 25, 2000

Does Allosaurus have other relitives?
from Raveena L, age 8, Cedar Grove, NJ, U.S.A.; May 24, 2000

hi cohnzie!! this is the best place for Dino info I should know I`m a tyrunna.................ttyrauhhhhhhhh.....................

britteny spears loves dinos
from maddy p., age 23, london, england, europe; May 24, 2000

I hadn't heard that before, Maddy. That's really interesting. Where did you learn it from? I will listen to Britney Spears music more carefully now to see if any of her lyrics are possibly about dinosaurs. I kind of doubt I'll find anything, but you can interperet a lot out of nothing when you really try.
from Brad, age 13, Woodville, ON, Canada; May 24, 2000

I realy like this can you give me a pictuer of you? t
from alex b., age 13, Indianapolis, Indiana, ?; May 23, 2000
No, I don't have any online. JC

Ooh! I read this site was for kids, does that mean I need to find an adult dinosaur site as I'm just learning about dinosaurs and this is the best site I found. Hope I'm still welcome to post here after all I'm still just a big ?
from Sharon, age 23, Manchester, Dunno, England; May 22, 2000

Wow, Brad you know so much about dinosaurs, I am still learning about dinosaurs I can barley remember all there names theres so many different kinds this site has the most information I've seen, my favourite dinosaur is the diplodocus, thanks for answering my last question
from Sharon, age 23, Manchester, Dunno, England; May 22, 2000

Thank you, Sharon. My main reccomendaion is to read books if you want to learn about dinosaurs. It took some searching, but I did eventually find the adult dinosaur book shelf in a book store, and they are awesome. They should be on the Biology shelf. They are expensive though. The biggest dinosaur website is, which has every dinosaur on it. So does Both have good image galleries, and the DinoData site has news (which I haven't checked recently, I better be going!) There are lots of other dinosaur sites, but very few message boards. Keep using this site, you will always be welcome.
from Brad, age 13, Woodville, ON, Canada; May 23, 2000

how fast was t.rex?I love dinosaurs alot.trex may not have been the big guy during the dionosaurs time.a new long neck named ultrasaurs is alot bigger than him.
from jason h, age 12, new kent, va, usa; May 22, 2000

Tough question, Jason. Some people have said that T. rex ran 40 mph, and some people have said it didn't run at all! 25 mph is reasonable as a top speed for T. rex. That is faster than a person. Ultrasauros was much bigger than Tyrannosaurus, but it was never around at the same time. It was actually found in the late 1970s, and was informally referred to as "Ultrasauus" with quote marks for about a dozen years. In 1985 a smaller sauropod accidentally became the type specimen of Ultrasaurus (probably bigger than T. rex though, as almost all sauropods are) so the famous ultrasaur became Ultrasauros in the early 1990s. It appeared by its scientific names in a few books up until 1997. Most of the top dinosaur sites, this one being an exception, now have Ultrasauros as an invalid name, since it is supposedly a SupersaurusBrachiosaurus combination of bones.
from Brad, age 13, Woodville, ON, Canada; May 23, 2000

I went to MCdonalds on Saturday, so I have two of the dinosaur toys. It appears that the hand puppets will be first, followed by the talking figures. The puppets are made of a very strong-smelling material. The first toy in the series is the Aladar puppet. It is a cute, comical looking dinosaur, but should not be called lifelike. Most oddly, his teeth seem to be modeled after human molars, not iguana teeth. Also, I do not think the Iguanodon had forward facing eyes, which Aladar has. His blue and peach colour scheme is not the greatest. Aladar is still a nice character though, despite his slight inaccuracies. The second toy, the Carnotaur, does look pretty lifelike, as it does in the movie. Actually, its downright scary. He's grey and red with little yellow eyes, and with lots of litle spikes and big horns. It's a much larger, tougher carnotaur than the carnotaur from the lost world finger puppet collection (which I own one set of), and co! uld probably beat up most Lost world toys if I gave it the chance. I can also tell you the other toys that were displayed. The other two finger puppets are two of the other Iguanodons, Neera and Krone (oficially Kron, though Krone is truer to the pronunciation used in the film). The three dinosaur action figures are the Brachiosaurus, Baylene, the Styracosaurus, Eema, and another Iguanodon, Bruton. Plus the lemurs, which is four lemurs connected into a single lemur family figurine. I expect the Dinosaur promotion to end on or shortly before June 16, the official start of the Beanie Babies promotion.
from Brad, age 13, Woodville, ON, Canada; May 22, 2000

i am creating lesson plans for my preschool class to prepare them for a trip to our dinosaur park. What do you think 3-6 year olds would want to know? And where can I find more information. I loved dinosaurs when I was a kid, but that was many, many years ago. any help will be very appreciaited. thanks!!!
from miss jenn, age too old, ?, ut, usa; May 21, 2000
We have dinosaur printouts to color. There are other actiities for young children.

Good idea, Miss Jenn. What type of park is this? I assume it is not cloned dinosaurs, but is it a model/robot exhibition, or a fossil site? I was informed about dinosaurs in grade two, when I was about 7. It was fun, but awful scientificly. The best advice is to keep little kids away from out-dated information. I was taught that Stegosaurus had two brains, and the Brachiosaurus could only survive in deep water, neither of which is true. I would teach them about the new record-setters, Seismosaurus (longest) and Argentinosaurus (heaviest), the new biggest meat-eater, Giganotosaurus, and other up-to date stuff. Try to find impressive facts like how much food large sauropods ate, and create a modern comparison that relates to the children. When discussing the size of dinosaurs, we measured across our classroom to see how it related to a Stegosauurs. And put in some old favourites, like Tyrannosaurus and Triceratops. Kids love those. If you w! ant to know what 3-6 year olds find so great about dinosaurs, just go to the vote for your favourite dinosaur section of and read what people that age write in.
from Brad, age 13, Woodville, ON, Canada; May 22, 2000

I got two new dinosaur books yesterday. The Children's Encyclopedia of Dinosaurs (Consultant: Professor Michael J. Benton, 2000) is a great deal better than its title sounds. I found this 95 page hardcover book for $9.99, making it less expensive than similar books. Its a pretty typical dinosaur reference book for kids. The age, size, classification, location and pronunciation of each dinosaur is given, as well as a paragraph about its anatomy, discovery, or possible behavior. There are over 100 different dinosaurs, plus the mammal-like reptiles, plus the prehistoric turtles, plus prehistoric lizards, plesiosaurs, icthyosaurs, early archosaurs, prehistoric crocodiles, pterosaurs... they squeezed a lot of information into this book. I even found the "new" dinosaurs like Scipionyx, Siamotyrannus, Suchomimus, and Protohadros that aren't included in most other books. There are over 250 full colour images, many of them illustrations by Steve Kirk.! Overall, this is a very nice book. Two claws up! More reviews to come...
from Brad, age 13, Woodville, ON, Canada; May 21, 2000

How smart was the Giganotosaurus?
from Geoffrey P, Fort Worth, Texas, USA; May 21, 2000; May 21, 2000

Its hard to tell, Geoffrey. THe Giganotosaurus had a brain half the size of a T. rex's brain. I think it has been described as the size and shape of a banana. Giganotosaurus could certainly outwit an Argentinosaurus though.
from Brad, age 13, Woodville, ON, Canada; May 21, 2000

by the way , Brad, are you going to see the dinosaur movie tonight? or did you already see it? I would like to know about how good it is because I might want to take my little sister to see it. Thanks!
from Jen, age 14, ??, NC, US; May 21, 2000

Hi, Jen! I saw the Dinosaur movie yesterday (saturday). Yes, it is a good movie. It is definately one to see in theatres. When the cameras move, it feels like the seats are moving. Its a very cool effect.
from Brad, age 13, Woodville, ON, Canada; May 21, 2000

Hi to everyone! This website is really cool and helped me with my project thanxs for the help and I will recomend it to all my mates!!!!! Charlotte
from Charlotte, age 14, Chale, Isle Of Wight, England; May 21, 2000

I just wanted to say that I was passing this site and decided t read the messages. I am really amazed with how much you guys know about dinosaurs. Especially Brad. I am only on this site because I have a project due for my science teacher this coming Wednesday. I am reaserching the following dinosaurs: Oviraptor, Cerotasaurus, and Pteradactylus. If anyone has any idea where I can get detailed pictures from I would greatly appreciate it. Thanks! I will check back for any answers later. Thanks again!
from Jen, age 14, ???, ???, US; May 19, 2000

Thank you, Jen. Be careful with the Oviraptor. I must warn you that most of our ideas on this dinosaur were recently flipped around, and to only use books coming form the later half of the 1990s. Just keep in mind, it was sitting over its own eggs, not stealing those of a Protoceratops! Maybe you already knew that. I don't have much to say about Ceratosaurus or Pterodactylus, you should be okay with them. The best way to get illustrations is to draw them! That way, they can look exactly the way you want, and they won't be plagarism! My teachers talk about plagarism all the time. You'll probably get better marks too. If you really can't draw, try There is lots of art there. Good luck!
from Brad, age 13, Woodville, ON, Canada; May 19, 2000

thanks for the help. Yes I did know that Oviraptor was sitting on it's own eggs. I think it's name is innapropriate but I got stuck doing that dinosaur. I will check the address and get back...thanks!
from Jen, age 14, ??, NC, US; May 21, 2000

I would find it very interesting to talk to someone aobut dinosaurs. Is there a chat room on this site? If not there should be, for live questions and answers. If there is, how do I get to it???Thanks!!!
from Jen, age 14, ??, NC, US; May 19, 2000

Not much dinosaurish happened to me today. My mom bought a newspaper with some dinosaur movie pictures in it, and they are so cool I'm going to use them a posters. I am going to the movie tomorrow. I have read many reviews of this movie, and there are so many diffent feelings. It is pretty much agreed upon that the visual side is great though. I can't wait to hear what all of the dinosaur's voices are like, the only one that talks in the tv commercial is Aladar. I wonder what the raptors will be like. From my limited understanding, they will play the role that the hyenas did the lion king- a lesser predator that does little more than tell jokes. I do kind of question this though, since it has been called a humourless movie. I'll definately be talking more about the movie tomorrow night, although I promise not to give anything away.
from Brad, age 13, Woodville, ON, Canada; May 19, 2000

Hey Guys. I just came to this site and well I'm kind of myterious. Well Dinosaur Jack isn't my real name. But here's some hints. My dad's a paleontologist and I've been on some of his expiditions. THAT MEANS I've seen real dino bones in person. My dad's a real expert. It's pretty cool.
from Dinosaur Jack, age ?, ?, ?, ?; May 19, 2000

That is so cool, Dinosaur Jack! I really don't know a lot about the families of palaeontologists. Are you by any chance Jason H.? I know he's been on his dad's expeditions. I'm waiting for the next clue.
from Brad, age 13, Woodville, ON, Canada; May 19, 2000

I'm totally facinated with dinosaurs, I heard a Velociraptor was only half the size of the ones that appeared in Jurassic park is this true ? Ooh! I feel to old to be posting on here somehow.. anyway hope you can answer my question.
from Sharon B, age 23, Manchester, Urm ?, England; May 18, 2000

Yes, its true, Sharon. The real Velociraptor was relatively small dinosaur that weighed about 30 pounds and was only 6 feet long. Other problems with the movie 'raptors are that the tails lack stiffening rods (watch them whip around), their hands are incorrect, they weren't really cheetah-fast or chimp-smart, and they don't have feathers (but that is probably the result of them being mixed with snake DNA or something, in my opinion).
from Brad, age 13, Woodville, ON, Canada; May 19, 2000

On this site, Longneck is treated as an informal name for Apatosaurus. But is that Littlefoot guy really an Apatosaurus? I think he has Camarasaurus features myself. The Land Before Time is quite a challenge for people who want to identify the dinos. The litlte fellow Chomper has three fingers, and looks like a Carcharodontosaurus. But his "parents" have two fingers, looking like Tyrannosaurus. Perhaps its just better to sit back and enjoy the stories. There may also be problems with disney's Dinosaur. From the pics I've seen, the character Kron looks like an Altirhinus (with the big nasal crest), but his "sister" is an Iguanodon (mantelli?). Its still going to be good.
from Brad, age 13, Woodville, ON, Canada; May 18, 2000

I produced two great dinosaur paintings today! We had art class, and we were painting flowers on felt. I made some violets with a Velociraptor hiding behind them! I am especially proud of the blending I did between the white, yellow, and red of the raptor's neck. The fuzz of the felt suggests protofeathers, without having to apply ugly, oversized plumage intentionally. This is not the JP raptor, btw, but the slender-snouted, dog-sized dinosaur of the fossil record. I'm not sure if violets were present in the Cretaceous, but there were likey some sort of small, blue flowers that raptors occasionally hid in. My second piece of art was to do the Einiosaurus painting, which I did in the evening. It is also very good. I like the background trees and lighting the most, since they are the best I've ever done. The einiosaur turned out grey, but it is still cool, with black horns. I will be entering it in a contest, and compared to the previous win! ner, I think I have a chance. Do any of you draw dinosaurs? Tell me about your latest works!
from Brad, age 13, Woodville, ON, Canada; May 18, 2000

No Brad, you are all mixed up. Its Tyrannosaurus thats42 feet long (40 is an approximation.Carcharodontosaurus was 46 feet long.
from Robert S., age 9, Lawerenceville, G.A., U.S.A.; May 18, 2000

No, Robert. Sue, a big T. rex, is 41 feet (National Geographic, Jun. 2000). I think some males weren't even 40 feet. 42 is possible, but not typical for T. rex. I'm keeping 40 feet for T. rex. Carcharodontosaurus is known from a skull, 5 feet, 3 inches long, but we don't know how long its body was. 46 feet is an upper estimate though. Reporters for magazines, televison and newspapers are tempted to exaggerate in order to impress the public. Books do usually say lower, or admit that it is unknown. We are still pretty close in our beliefs, so there is no real reason to argue. If you know the name of the 42-foot rex, tell me.
from Brad, age 13, Woodville, ON, Canada; May 18, 2000

what kind of animal do fly?
from melissa w, age 12, haverhill, Mass, ?; May 18, 2000

Not dinosaurs, Melissa. Flying animals include insects, pterosaurs, birds, and bats.
from Brad, age 13, Woodville, ON, Canada; May 18, 2000

I saw the McDonalds dinosaur toys on tv! A family are eating at McDonalds, and they have some of the toys. The boy puts a lemur figurine on his sister, who tells him ot take it off of her. He then puts it on a ceratopsian (pachyrhinosaur, perhaps?) action figure, and hears a phrase from the movie. Pretty high-tech from McDonalds, I'd say. You then see the complete collection of four dinosaur head puppets (which I am pretty sure includes Carnotaurus), three dinosaur action figures (the ceratopsian, brontosaur (Alamosaurus?), and one I didn't catch), and the lemur family figure.
from Brad, age 13, Woodville, ON, Canada; May 18, 2000

You can find plenty of dinosaur info in books
from Jonathon, age 10, Hillside, Ill, North America; May 18, 2000

Absolutely, Jonathon. My library teacher has warned our class numerous times, mostly unnescessarily, that the internet contains lots of inaccurate stuff, so I do like seeing the new dinosaurs in books. The interent is still great to communicate about dinosaurs, though!
from Brad, age 13, Woodville, ON, Canada; May 18, 2000

can a t.rex able to kill an apatasaurs?
from Jessica, age 10, dumont, new jersey, united states of amarica; May 17, 2000

Not a chance, Jessica, for the same reason that you cannot kill an Apatosaurus- Apatosaurus was already extinct before the T. rex ever existed.
from Brad, age 13, Woodville, ON, Canada; May 17, 2000

I just finished my pencil drawing of Einiosaurus. The einiosaur in the foreground is using his horn to scrape the bark off a tree and is also chewing on some bark. There are many bent and falling trunks in the background, evidence that dinosaurs have came crashing through. There are amber beads with mosquitoes on one of the trees. In the background, you can see sunlight penetrating through the canopy of the forest, and the shape of another einiosaur pushing a tree trunk with his beak. I realy like this scene, and I want to make a painting of it. Any suggestions for the einiosaurs' skin colour?
from Brad, age 13, Woodville, ON, Canada; May 17, 2000

I just won't to say this is a wonderfull program. I really know alot about dinosaurs.

What was the name of the oldest dino?
from Kristi T., age 12, Brookport, Illinois, North America; May 17, 2000

I'm not sure Kristi. Those Madagascar prosauropods are often said ot be oldest now, and they are nameless. However, these forms did not occur in radioactive-type rock, and cannot be dated with accuracy. the 235-230 million years old is an estimate based on the general primitiveness of other animals at the site, but who really knows? Maybe Madagascar was sort of a lost world where primitive life forms existed 10 or 20 million years after they disappaered elsewhere. However, having mTr anchisaurs, and Pisanosaurus as a possible heterodontosaurus is great for Bakker's Phytodinosauria, so I hope this does turn out the way it seems. But to get back on track, its Eoraptor, dated at 228 my old using volcanic ash from the site.

Hello,I was wondering how long did the homalocephale live????
from Christen G., age 13, ??, IL, USA; May 17, 2000

I have no idea, Christen. Homalocephale was maybe a few hundred pounds, and lifespan is said to be roughly related to age, though I myself kind of doubt this. I do know a dinosaur website that can calculate lifespan from mass, so I'll try it for you.
from Brad, age 13, Woodville, ON, Canada; May 17, 2000

Okay, Christen. First, I calculated the weight of Homalocephale between 200 and 385 kilograms. That's about 440 to 840 pounds, about right for a 10-foot long herbivore with a huge flared gut for digesting a lot of plants. The life span is about 40-50 years, although the actual range I got was 20-80. You also had to choose mammal-like or bird-like phisiology. I choose to lean towards mammal-like, since the lifestlye of Homalocephale is presumed to be like that of sheep or goats.
from Brad, age 13, Woodville, ON, Canada; May 17, 2000

Sorry Christen, but I way overestimated the weight of Homalocephale. I believe I used the length of the femur instead of the circumference (I used the number 218 mm, 21.8 cm- yeah, its probably length)- that would probably do it. Anyway, the Pachycephalosauria website has it at 26 kilograms (a mere 57 pounds) and 2 metres long. I used that number instead, and calculated 16 - 33 year lifespan. That does sound more reasonable, since most animals don't live long compared to people.

Hey ya'll. I don't know you Brad but answer me this. I have some complaints. Charcharodontosaurus, wasn;t he smaller then T-rex. I mean I've seen magazines with him stated to be larger than Rex but in some books I own it says Charchar was smaller. I'm having a breakdown about this. And since I've been reading and you seem to know alot I'll ask you. And Seismosaurus WAS 52m long and Supersaurus wasn't that long. Help me out on that if you can. Thank you and this is good bye from Dinosaur Jack.
from Dinosaur Jack, age ?, ?, ?, ?; May 16, 2000

Hi, Dinosaur Jack. Your complaints are certainly reasonable. The first Carcharodontosaurus fossils were collected in the 1930s, I think, and were pretty fragmentary, just some odd teeth and bones. They were from an animal about 26-33 feet long, right? Around there. The magazines are referring to a 1996ish discovery of a skull about 5.5 feet long, from an animal about 42 feet long. A little bigger than a rex. I don't think there has been any arguments over whether the skull belongs to the smae species as the type specimen, since this animal was named for its distinctive teeth, after all. Carcharodontosaurus just a big size range, it seems. And both Seismosaurus and Supersaurus are too poorly known to give an accurate length. Seismosaurus is known form only its back end, and Supersaurus is known from... uh, I forget. I'd get my books but my sister will be bugging me shortly to get off of this site. Anyway, they're both about 120 - 150 feet.! 52 metres is like 170 feet, which is about the upper size estimate of both of these animals.

Nice to hear from you again, Robert. Those are some pretty big theories, but that's what this place is all about, isn't it? Let's see if I agree with you. Giganotosaurus teeth were described in National Geographic (Dec97) as being perfect for slicing up flesh and making animals lose a lot of blood- not really an adaptation a scavenger would need. but if Argentinosaurus died, Giganotosaurus would be pretty stupid not to scavenge. Feathers, feathers. The only one I'm in definate agreement with is Utahraptor, and even that one I'm sort of ... uh, not fond of. I just can't see a 1000-pound raptor with bright, elaborate plumage, although protofeathers are a maybe. In my mind, birds and raptors spilt before true feathers, the raptors retaining protofeathers. I regard Dilophosaurus as too primitive to have any feathers, mean, its a ceratosaur. Megaraptor, even as a coelurosaur, would not have to be feathered. Albertosaurus was a coelurosaur of a! bout the same size, and it was not feathered. Megaraptor could possibly have resembled an ornithomimid, except ornithomimids have very lightly built feet and I'm not sure if they could use their claws in that way. Babmiraptor Rahonavis link? Yes, i'd agree with that, but partially because I know very little about either of them. You seem to know a lot, so maybe you know something I missed her. Over all though, some good new theories have been made. Well done!
from Brad, age 13, Woodville, ON, Canada; May 16, 2000

Giganotosaurus was a scalvenger.Dilohosaurus,Utahraptor,and Megaraptor had feathers.Megaraptor resembled Ornithomimids. Bambiraptor was related to Rahonavis and was the smartest Dinosaur.

I understand about the e-mail, and I'm okay with it since we can just say it here anyway. But what about home page adresses- is that okay? Jay the Dino Master is making one, and I will be writing some of the content. It will be a dinosaur site. Can we post the adress here when we're done?
from Brad, age 13, Woodville, ON, Canada; May 16, 2000

Yes, if you have your own website, you can put your URL online. JC

Hi, Jay the Dino Master! Welcome to Dino Talk! Is being a dino master like being a pokemon master? That would be kind of cool, collecting little dinosaurs and battling them... oh, I actually do that. Remember to share all of your crazy theories we used to talk about, and any new ones you might have! I hope you get lots of replies! :)

can some one help me learn about dinsaurs
from lizzie f, age 9, manchester, chesire, england; May 16, 2000

I could, Lizzie. Just tell me which dinosaur type or dinosaur issue you want to learn about, and I'll try to tell you facts about it.
