allosaurus is much larger than tarbosaurus
A T-Rex of coures, because a T-Rex is bigger than a Allosaurus alot, and have a more powerful bite

A stegosaurus is a much slower paced critter than an allosaurus and therefore cannot run faster.
The T-Rex is bigger than the Allosaurus though the Allosaurus was the biggest carnivore of it's time but the T-Rex is still bigger
Mapusaurus
Allosaurus would probably wind. Velociraptor was much smaller than their depiction in Jurassic Park, was no bigger than a turkey and probably not do much damage to Allosaurus, which was nearly as large as T. Rex.
The height to the top of an Allosaurus's head was nearly 10 feet. That makes them slightly taller than an Indian elephant.
Allosaurs was 28 feet long and weighed between 2,200 lb and 8,800 lb, depending on the estimate you use. Ceratosaurus was about 22 feet long, and depending on the weight estimate you use, they would have been between 606 lb and 996 lb or 1,160 lb and 2,200 lb. In any case, Allosaurus was much larger than Ceratosaurus and thus was probably far stronger.
The height to the top of an Allosaurus's head was nearly 10 feet. That makes them slightly taller than an Indian elephant.
There is one accepted species in the Allosaurus genus. Its full Latin (or scientific) name is Allosaurus fragilis.
