Phobosuchus, which is a synonym for deinosuchus was a large alligator-like reptile that ate dinosaurs in the cretaceous.
In Animal ArmageddonEdit
Doomsday A few phobosuchus were shown eating some hadrosaurs just before the asteroid hit.
Aside from using a different term which is not a true error the snout of phobosuchus was too narrow. Not as narrow as Sarcosuchus but still not as broad as it is supposed to be. Also they were shown during the K-T extinction when they really lived earlier.
