Allosaurus feeds on smaller prey like Gallimimus or Moschops, they have the capabilities to hunt larger prey like Amargasaurus or Parasaurolophus as they have little defenses. Allosaurus hunts in a "wavy" pattern, and jumps at its prey.
Allosaurus has a reddish back and a very natural look, which makes it blend in very well in most Central Sector islands.
Allosaurus appears in Carnivores, Carnivores 2, and Carnivores: Dinosaur Hunter. An Allosaurus-like creature appears on the art of Carnivores: Dinosaur Hunter HD, and Carnivores: Dinosaur Hunter Reborn, but do not appear in the games.
Allosaurus barely looks like it's Earth counterpart, but the part above the eyes is slightly like it's counterpart.
