Antrodemus

Antrodemus is a type of large theropod dinosaur from the Morrison Formation of Utah. Antrodemus co-existed with many other large carnivores of the time, such as Ceratosaurus, Allosaurus, Torvosaurus, Stokesosaurus and Ornitholestes. It also shared this area with gigantic plant-eating dinosaurs such as Apatosaurus, Camarasaurus, Brachiosaurus, Diplodocus, and the primitive sauropod Haplocanthosaurus.
