Who would win an allosaurus or an t-rex?

Answer 1

It is always difficult to gauge who would "Win" when 2 animals never came in contact with each other.Allosaurus live in the late Jurassic Era between 155 and 145 million years ago and Tyrannosaurus Rex lived in the late Cretaceous period 68 - 65 million years ago. The last allosaurus died 77 million years before t-rex evolved.

It becomes even more difficult when you consider that we know absolutely nothing about both they're behaviour's We can however look at the evidence and make few educated guesses. It looks likely that both species were top predators of there own times. T-Rex was the bigger of the 2 at a length of 12.8m, standing 4m high and weighing probably about 6.5 tonnes compared with the largest species of allosaurus at only 8.5 m in length and weighing 2.5 tonnes. This would suggest that allosaurus would be more agile than t-rex but would sustain far more damage if t-rex managed to catch it.

It is also believed that t-rex had the largest bite force of any animal to ever exist on earth. Allosaurus however could not ever come close having a bite forse probably less than a modern day leopard. Other factors would also be significant. If you compare the skulls it would suggest that t-rex had very good binocular vision and also a large visual area of the brain, much more than allosaurus had limited binocular vision and a small visual cortex.

It is also thought that t-rex was faster than allosaurus. You also have to consider what prey they ate. Evidence suggests that allosaurus ate Sauropods, the largest land living animals of all time. Quite simply there were no dinosaurs larger than T-Rex at the end of the cretaceous. Evidence suggest that animals such as Triceratops. Allosaurus certainly had the edge here. However, if i was forced to put a wager on which would win i would my money would be on T-Rex.

Answer 2

a Trex would win because it's bigger has a stronger bite and has serrated teeth
