Ankylosaurus
Ankylosaurus is a genus of ankylosaurid from the very end of the Cretaceous Period (between about 66.5–66 Ma ago) in western North America. Although a complete skeleton has not been discovered and several other dinosaurs are represented by more extensive fossil material,Ankylosaurus is often considered the Archetypal armored dinosaur. Other ankylosaurids shared its well-known features—the heavily armored body and massive bony tail club—but Ankylosaurus was the largest known member of the family.
Tyrannosaurus

Tyrannosaurus Is a genus of coelurosaurian theropod from the cretaceous of north america. Like Other tyrannosaurids, Tyrannosaurus had a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, Tyrannosaurus fore limbs were short but unusually powerful for their size and had two clawed digits. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it was the largest known tyrannosaurid and one of the largest known land predators. In fact, the most complete specimen measures up to 12.3 m (40 ft) in length up to 4 metres (13 ft) tall at the hips,and up to 6.8 metric tons (7.5 short tons) in weight.

Anky takes this IMO. I think anky would just be too much for any theropod. It's just to heavily armoured.
65-35 for anky.

Depends on the situation. Two Rexes, Rex obviously had a better chance. A standard situation, Anky every time. Rex would have to be desperate to even think about challenging an Anky.

it may be armored, but it's tiny compared to tyrannosaurus(and the other theropods for that matter)

In that scale is the Ankylosaurus with the largest skull, and i believe the tyrannosaurus is sue.
Also, there was a study conducted rather recently that showed Anky's armore was much closer to kevlar(the stuff they make bullet proof vests out of) in structure.
Keep in mind Tyrannosaurus was well adapted to taking out armored prey, it had the dentition and the evolutional intelligience to know how to deal with Anky

Well, given that info, probably 60-40 Rex. Call me a Rex Fan extremist, but with that info, that's what I think.
Jack of all trades. Master of none

With the new sizes I think it has to go to the rex, the size difference is too much. I think the anky wouldn't do as much damage as we thought! So 60-40 also :p

Here's the article on the study:
Ankylosaurus: the bullet proof dinosaur
Walking With Dinosaurs inflated its size to 9/10 meters in length, and made it an impenetrable beast. In reality, Anky was 7/8 meters, 3 tons in weight. It would have no problem with the other predators in its environment(Nanotyrannus, Dromaeosaurs) but rex was a different matter.

I'm going 60-40 Rex. From that info, ankylosaurus stands no chance. It's way too small compared to rex. I remember hearing how unuseful the tail is because it's disproportionately short.

I'd say 50 50. While anky was small and rex was specialized at taking down heavily armoured prey. Ankysaurus armor I'd say would be almost indestructible I doubt a rex could bite through the armor. To be honest I'd say they stayed away from each other.

In normal situations and probably most, id say Anky close to evertime, a Rex would just have to get lucky enough to flip it over without getting nailed by the tail, or even getting stabbed by its side spikes. So either way, if Rex kills it or not, its in for some injury.


S-P, stepping on an Ankylosaurus would be as much logic as stepping on a lego.

For the most part, they'd just ignore each other. Anky was a tank, but at the same time, too small to be worth the effort. If they did end up fighting, it is possible for Rex to have been able to bite through Anky. Rex's bite force has been estimated at 3-9 tons PSI. That's the equivelent to about 6 000 to 18 000 pounds PSI. Now, some may say Rex had a bite force topping at 7 tons. That's still 14 000 pounds PSI.
To give you an idea on that, a .50 BMG round produces about 2000 foot pounds of energy. That's 2000 pounds of force over a square foot. That's enough to rip a hole in an engine block. So, upwards of 10 000 pounds of force over a square inch would probably do the job.

That would be like biting on a hardwood tree with spikes, i doubt it would ever chance that unless its hallucinating from the lack of food.

@Ya and stepping on a Lego would crush it.
and please call me raptor or rex or something.

As Mr. H said, it depends on the situation. 2 Tyrannosaurus vs. 1 Ankylosaurus, the Tyrannosaurus wins. 2 Ankylosaurus vs. 1 Tyrannosaurus, the the Ankylosaurus wins 1 Ankylosaurus vs. 1 Tyrannosaurus, it could go either way, but Ankylosaurus would probably win. However, they would most likely ignore each other.

Why do you change your name so much? Youve only been here almost a month and youve already made 3 names, and Raptorexx is already taken by another.

Which is why I said that for the most part, they'd ignore each other.
It's the "what if" factor that people like to discuss. Rex and Spino for example, it's always people arguing about if they actually fought. What they don't argue about is the difference in diets that would allow them to just ignore each other. It's the "what if they fought?" that people like to talk about, not the "why would they fight?" bit.

And if rex tried to flip it it would recieve side-spikes to the face... Honestly, despite anky's small size, it was nearly impossble for a rex to kill it. If it laid flat on the ground, a rex would be hard pressed to flip it, and like spino said, Ankylosaurus was a lego. You do not step on it. So... That leaves us with one hungry rex vs. one irritated ankylosaurus.
Another way to look at this is like an armadillo and a coyote. It'll take a lot of luck for the coyote to win, and it's better off looking elsewhere for food.
Here, have a waffle (-'.')-#

SP, have you ever stepped on a LEGO? No, they do not get crushed. They cause the most unbearable pain you'll ever feel.
Jack of all trades. Master of none

Well we do argue about Spino's diet about as much as Rex vs Spino, but that also.

@ spino rex, I get bored of them.
and if the size chart is accurate I don't see why rex would win with Ease. It is adaptted to taking armored prey. The worst that could happen to rex is a cracked shin.

That is true. I think we can all agree that, when fish were plentiful, it ate fish. Any other time, perhaps scavenging and hunting some Hadrosaurs. The young, old, weak and sick, like any predator would go for.

WAIT! Cease this spino nonsense immediately. This is rex vs anky. Do you see a spino in there? NO. Now stop.
Here, have a waffle (-'.')-#

Well you already know my opinion on the deal, so ill just leve it at that.

Same here, sorry, it was an example. Sorry again, forget that happened.
Jack of all trades. Master of none

You are right SF, i wasnt the one to bring it up though, just pointing that out.

And Mr happy I have steppedon one and it hurt. But if you are wearing a Aho and are a large Pearson n and want not crush the Lego it will be crushed.

@Spino I understand that, just didn't want this topic to get closed.
Anyway, as I said, my opinion on this is that it's like a coyote trying to get an armadillo. It might, but it's generally not worth the effort. So I say that neither wins. It is a draw.
Here, have a waffle (-'.')-#

SP, please, just please work on your spelling and grammer, it shouldnt take me 30 seconds to figure out one statement.

S-P wether you way 100 lbs,or 350 lbs your not gonna crush the lego... Also the reason people aren't calling you "raptorrex" is because that name is TAKEN.

Wait,dynamosauruas imperious?
I will Change my name cause he had it first.

that got...random..
Well, this was a predator/ prey relationship. Anky got more defensively built as the years rolled by in the thousands/ millions, and rex developed bone crushing dentition. Though the prey of choice was probably hadrosaurs(Edmontosaurus regalis), Tyrannosaurus wouldn't pass one of these guys up because it has the weaponry to deal with it. But, do take into effect most land predators today have a ~30% of actually capturing and killing their prey, so this isn't going to be an easy meal in more then one way.
I'd have to say50/50 with the slight edge to the anky.
Nature doesn't deceive us; it is we who deceive ourselves.

Well, i suppose if it could get ahold of its neck, it wouldnt have to worry about getting hit by its tail, which ultimately means the end for Anky due to having no protection under its neck, and the armor on top of its head and neck would amplify the damage under its neck.

In my 50/50 scenario, That's not even resulting in death(for the rex anyway) Most times, a Tyrannosaurus wouldn't be able to get at the underbelly of this thing, and there's no way i see it flipping the anky over. Anky's defenses were more deterents then ofenssive defense, it's tail is disproportionally short in retrospect to its body, and while i haven't read anything on the range of motion the ankylosaurus' tail had, i doubt it was very signifigant.

Actually thats the case with most animals that have those accesories, like the thorned lizard, which is simply most of the time more of a "do i look appetizing to you?" kind of thing.
