On Triceratops, there are some really fasinating things to note. In contrast to old arguments of Triceratops galloping at 45 kilometers an hour, recent looks into it's limbs, which have the front limbs sprawing (which have been poorly understood anyway, having reconstructed with some hardosaur parts in the first place!) indicate that this was quite a slow animal indeed. Not painfully slow, but no where being able to gallop or charge a Tyrannosaur sucessfully. That removes it's main and most commonly assumed method of defense, by charging a Tyrannosaurid. The horns are another problem, though impressive, were positioned quite far out of the way to be brought in usefully in a pitch (the animal had to lower it's head a great deal, totally removing it's targer from sight, leaving it ignorant and vulnerable to attack if the predator sidesteps of moves out of the way). A lone Triceratops would have little chance of standing up to Tyrannosaurus one-on-one, but one thing about the animal was that it could most likely change facing extremely fast, so the idea of Triceratops defense was more passive then active, constantly facing the predator rather then charging (assuming the predator didn't have the advantage of surprise). A charging Triceratops would most likely miss the target and get flanked anyway. I believe Triceratops was more of a team-player in survival, rather then an animal capable of taking on Tyrannosaurus one-to-one.

"but it's thighn bone is longer than it's shin bone making it a slow runner"

I really wonder where you are getting this from, because Tyrannosaurus had extremely gracile limbs, measurement for measurement, compariable to that of modern ostrichs. If you want to look at an animal with extremely long upper limb bones and short shins, look at the raptors, commonly and misguidedly considered "fast" runners. I wonder where on earth Horner got his "measurements" for Tyrannosaurid limbs from anyway. when he was immediately refuted by another paleontologist who had done specialized work in that matter, Tom Holtz.

I don't think a T Rex standing on an Anklyosaurus would do much (if any) damage to the anklyosaurus. Anklyosaurus armor was VERY strong and the T Rex would probably get stabbed by the spikes on anklyosaurus's armor. And it would be very hard for a 12 meter long T Rex to dodge the anklyosaurus's tail and the t Rex wouldn't risk it anyway because if the anklyosaurus did get the T Rex it could easily kill the T Rex.

"healed over grooves"

from da masta, age ?, ?, ?, ?; December 14, 2001

"Then start believing, for such a specimen has been known for sometime now."

You're absolutely correct Ten - Shun. But it's nowhere near the only specimen! There's a triceratops femur, (or pubis, I can't remeber,) with T - Rex tooth marks, and a trike frill with T - Rex tooth dents.
from da masta, age ?, ?, ?, ?; December 14, 2001

"Plus, all the scintific evidence...."

What "scientific evidence"? I hope you are not referring to the dribble Horner spews out. Yes, there is evidence of T.rex feeding on its contemporaries, Triceratops and Edmontosaurus; but whether it killed them or not is very difficult to conclude.

"...points to the fact that TRex was a scavenger."

Studies on the energy needs of a 6 1/2 ton adult Tyrannosaurus rex indicate that it would be impossible to meet its needs on an purely scavenger lifestyle. It would simply not find enough meat before it expired of hunger.

"If we ever uncover a dinosaur with healed over grooves in its bones from a TRex tooth, then I'll be a believer."

Then start believing, for such a specimen has been known for sometime now. And I quote :
"Carpenter, on the other hand, has provided solid proof of predaceous behavior, in the form of an unsuccessful attack by a T.rex on an adult Edmontosaurus. The intended prey escaped with several broken tailbones that later healed. The only animal with the stature, proper dentition, and biting force to account for this injury is T.rex." (Scientific American Book of Dinosaurs, Breathing Life into Tyrannosaurus Rex, p.274)
from Ten-Shun, age ?, ?, ?, ?; December 13, 2001

I don't think it would be worth the TRex's time or energy to hunt down trikes. It was just too dangerous of a proposal. Predators in the wild get knocked down and run over all the time. Such a fall could be fatal for TRex. It was most likely a scavenger. However, that doesn't mean that it was not a dangerous dinosaur. Plus, all the scintific evidence points to the fact that TRex was a scavenger. If we ever uncover a dinosaur with healed over grooves in its bones from a TRex tooth, then I'll be a believer.

"trex is my third favorite dinosaur now. what's this about it attacking slow prey?"

It probably tried to pick off slower individuals. It went for the easiest targets, it's quite logical to do that, from it's point of view. Even if it had ultra - powerful jaws.
from da masta, age ?, ?, ?, ?; December 13, 2001

"the t-rex did have the most powerful bite of all time, but it's thigh bone is longer than it's shin bone making it a slow runner"

Yes, but it had very powerful, strong, and gracile legs, so it probably didn't run very fast, about 34/kmh (still much faster than an olympic sprinter;) but could probably maintain it's speed for a long time, it probably ran down hadrosaurs and trikes, when they where dropping of exhaustion the jaws of T - Rex where upon them.

I have this "theory." When lions hunt buffalo, a very strong and dangerous animal, responsible for many human deaths, they try to panic the herd, break it up and make it run. If the buffalo stand up to the lions, the lions can't do much, but if the lions succeed in panicking the buffalo, and they stampede, the lions can pick off a slow andividual, separate it from the herd, and bring it down. So T - Rex probably roared at trikes, to scare them and make them stampede. It couldn't stand up to an angry wall of horns, but if the trikes ran away, the T - Rex could keep up behind them. Trikes had short, robust, but strong limbs, so they could probably maintain speed for a short while. When individuals start to tire, and end up at the back of the herd, separated, the T - Rex could strike, bringing it's super - powerful jaws into play.

from Tim M., age ?, ?, ?, ?; December 7, 2001

A good deal of Ankylosaurid fossils are found flipped on their back though!
from ?, age ?, ?, ?, ?; December 7, 2001

Actually, it's pretty easy for Tyrannosaurus to defeat Ankylosaurus. Ankylosaurus may be 3 tons heavier then Tyrannosaurus, being built for bulk, but the trick is getting to that size. When it was young, Ankylosaurus most likely suffered massive losses before getting to the adult stage, when their armour was not thick enough and they were too slow to run away. When young, Ankylosaurus must have been incredibly vulnerable, lacking the speed to run away and having the protective parent (if they had any) too slow to handle an attack from a Tyrannosaurus. No wonder they were rare. Prehaps Ankylosaurus didn't take care of it's young at all, it just laid a mighty number of eggs to leave to the predators, in hope that at least one or two would make it through.

I am not starting a battle or debate.I mean some scripts I saw were certainly not good.Some t-rex fans,long time ago said that all dinos became extinct because t-rex ate them up I don't think that is educational.Its always t-rex here and there every dinosaur would lose.The only other type of dinosaur able to defeat it,is another tyrannosaurus.Why did dinos grow amour and stuff?They weren't useless you know.Would tyrannosaurus be able to survive a large number of scrathes blows and stabs all at once?
from Donovan c, age 12, ?, singapore, ?; December 5, 2001

Yes, I concur with John. I think Ankylosaurus could be too much for a T-Rex, judging by the armor and club tail. One of the few ways T-Rex could have killed an Ankylosaurus would be to flip it over, but that would be difficult. Of course, T-Rex didn't try to hunt Ankylosaurs, unless it was starving...
from Tim M., age ?, ?, ?, ?; December 4, 2001

"Was there any dinosaur that could beat t-rex?"

Out of the many dinos found, there is very little that could kill t-rex. The only thing that could probably kill t-rex is other t-rex's. If a t-rex was juvinall then more dinos would have a better chance. Triceritops probably could kill rex accasionally, and the same for anklysaurus, I don't think rex would try to kill an anklasaurus though. That's probably it until new dinos are discovered.
from T-master, age ?, ?, ?, ?; December 4, 2001

Yeah, everything can beat a T-rex....when they're hatchlings of course. When you mean adult I think other rexes or maybe triceratops(though more ofen rexes kill them)because if they never died they would still be around today.
from Diloph, age ?, ?, ?, ?; December 4, 2001

"Is there any dinosaur able to defeat t-rex?"

Not fairly and squarely, T.rex could easily kill almost any dinosaur it faced (including the supersauropods). The only animal I can think of that can put up solid resistance to T.rex is Ankylosaurus and co., who were specicalized themselves to the extreme to defend themselves against T.rex. But even they were not entirely immune to Tyrannosaurus.

"mostly ever t-rex found has at least on trike horn in it."

Really? All the T.rex fossils I know haven't been noted to show this feature, you should think it makes the news.

"Don't get me wrong, I ment the Trike frill in the T-Rex corpolite. If paleontologists really did find evidence that a T-Rex had bitten through a Trike frill I would believe that."

Actually, I think they were refering to one Triceratops skull with a huge chunk taken out of the frill from a Tyrannosaurus rex bite (just about the only animal that can do that). Some have speculated that the bite was actually caused by the Tyrannosaurus when it bit a Triceratops on the head in defense to prevent itself from being stabbed during an attack. But notice the word here is speculated.

A triceritops would be a tough challenge for rex, mostly ever t-rex found has at least on trike horn in it. but then again, a lot of trikes found have rex bites in them. T-rex had an awsome bite, and could slice through trike bones like a knife going through butter. Triceritops probably killed rex but not as many times as rex killed triceritops. And a ton of rex dung has had trike bone. But through many movies and stories, triceritops and rex have been arch enemeys.

"T-rex couldn't manage to defeat an angry Triceratops on the run,didn't it? Please welcome the new king of the dinosaurs."

Sadly, you spoke too soon. Apparently T-Rex was more powerful as you thought as they found Triceratops frill bones in its dung. Man, you have to be one tough and cool dino to do that to a Triceratops, being able to bite through its frill and then survive to pass it out. A Triceratops skull has been also found with a T-Rex bite mark that destroyed a large area of the frill. Scientists determined that the wound was caused while the animal was alive and during its last fight, where the T-Rex bit it on the head FROM THE FRONT to prevent itself from being stabbed, apparently it was sucessful for the Triceratops was found throughly eaten and no sign of any T-Rex fossils around indicated that T-Rex took no losses in that fight. Yup, Triceratops died constantly under T-Rex. Hardly call Triceratops a king, it was among the most dangerous of herbivores but hardly a match for T-Rex. T-Rex probably got a 100:1 kill loss ration on that thing.

"T-rex couldn't defeat an angry Triceratops on the run..."
Triceratops was certainly challenging. Now Paleontologist believe it could run fairly fast when charging an enemy, much like the modern day Rhinoceros. But T-rex could defeat a Triceratops.
The T-Rex bursts out of the trees and bites down hard and kills the Triceratops. In any case, T-Rex could kill a single Triceratops, but when they were in herds it was a dangerous task even for T-Rex.
