The Tyrannosaurus Rex’s primary diet included both small and large animals. Scientists believe that this hulking beast whose name means “tyrant lizard” could eat up to 500 pounds of meat in one bite. Two or three humans would have been a mere bite-sized snack for the T-Rex. Fossils of the T-Rex’s prey have included the Triceratops and Edmontosaurus.
These prey fossils have given scientists the information that the T-Rex crushed the bones of its prey as it ate. Scientists have also found crushed bones of the T-Rex’s prey in its fossilized dung. The T-Rex probably chased its prey taking huge bites of its flesh eventually inflicting a mortal wound that would have killed the animal before being completely devoured by the T-Rex.
