Furthermore, Henderson suggested that "Ceratosaurus" could have avoided competition by preferring different prey items; the evolution of its extremely elongated teeth might have been a direct result of the competition with the long-snouted "Allosaurus" morph. Both species could also have preferred different parts of carcasses when acting as scavengers. The elongated teeth of "Ceratosaurus" could have served as visual signals facilitating the recognition of members of the same species, or for other social functions. In addition, the large size of these theropods would have tended to decrease competition, as the number of possible prey items increases with size.
