Saurophaganax is very similar in appearance to another, more famous meat eating dinosaur, Allosaurus except for a few important differences. Most obvious, Saurophaganax was much bigger, measuring over forty feet long. Some scientists thought that Saurophaganax should actually be lumped into the Allosaurus genus which would change its full name from Saurophaganax maxius to Allosaurus maximus. However, Allosaurus and Saurophaganax each have differently shaped vertebrae. This proves as a steep enough difference between the two to keep them separate according to most scientists.

Saurophaganax is one of the biggest meat eating dinosaurs of all time and is the official state fossil of Oklahoma. When it was alive it may have hunted the sauropod, Apatosaurus, for food since remains of both of these dinosaurs have been discovered from the same area in Oklahoma.
