Fight Request

I don't see how Rex could take it down. It was tall enough to easily walk over even the biggest theropods. What are the Rexes gonna do? Chew its knees off? Doubtful. They aren't small enough to climb its tail and aren't big enough to take its neck or legs off.

These tyrannosaurs will be at the maximum possible size. 65 ft long and 15 tons or so. Remember, a Rex that is 43-50 ft long and 7-10 tons has a bite force of up to 9 tons! Scale that up to a Rex 5-8 tons heavier, you're talking a bite force comparable to Megalodon, at 15-20 tons! That's massive. Also, keep in mind that, while Amphicoelias was really long, anywhere between 150-220 ft long, it was a diplodocid. Keeping that in mind, it probably only weighed 50-70 tons. Still massive, but a sauropod with the build of a titanosaur for example would probably weigh well over 100 tons with a length like that. All I'm saying is that, while Amphicoelias may be the longest sauropod, it may not have been as heavy as most think. Still gigantic. I think the fight would be pretty good. *Side note- Amphicoelias probably only had a head height of about 35-40 ft, not much taller than a 20-23 ft tall Rex. And a tyrannosaurus that is 65 ft long would be even taller, 30 ft or so.

No way. Amphicoelias would be at least 100 tons. A 65 foot Rex would only be about 25 feet tall and Amphicoelias would be 40. I think the whole 65 foot Rex thing is ridiculous. This isn't complete fantasy warfare and 50 feet should be the maximum allowed size for Rex vs Amp. Still, one hit from a tail or one stomp from those massive feet and Rex is done. Even with a pack, Rex stands little chance.

With coronation planned tactics and team work a pack of rexes could bring one down, rexes did travel in packs, we already sealed the lid on this... fight's still open... total count (that was clearly stated) yes 5 no 1

Also, we are using the biggest possible size for Tyrannosaurus. Even I don't think it was very likely, but we do have to level the playing field a bit.

Ok, even with all this, A. T. rex can't plan attacks. B. the sauropod is huge, even if it is light, it would still be 100 tons. C. The sauropod would be too tall for T. rex to attacks, they could attack legs, but the sauropod would just have to kick and by by T. rex. And one more thing, T. rex is not suicidal, crazy, strong, and confident, but not suicidal.

I think Tyrannosaurus was smarter than you realize. For one thing, it lived with giant sauropods, Alamosaurus. It may not have been as big, but T-rex would still have some experience with fighting sauropods. Also, Tyrannosaurus was the smartest of the large theropods. Not raptor smart, but smart enough.

T. rex is fairly smart, but I don't think it has the pack hunting expirience it needs to take down a huge sauropod. They were so big, they only would need one or two rexes to go out and hunt at a time. The others would stay and babysit.

Perhaps, but in the end, it really is just speculation. I'm sure we can all agree on that.

You're right, name one thing we really know about dinosaurs.

They existed, haha. That's about it.
