About the smae size as the much more famous Tyrannosaurus, saurophaganax was larger than the more popular, Allosaurus. It had a crest on its head, also like Allosaurus. It was a very dangerous predator, and could easily steal a meal from the, way smaller Allosaurus. It was also, only slightly smaller than the huge Carcharadontosaurus.
