 Other evidence suggests hunting behavior in Tyrannosaurus . The eye @-@ sockets of tyrannosaurs are positioned so that the eyes would point forward , giving them binocular vision slightly better than that of modern hawks . Tyrannosaur @-@ inflicted damage has been found on skeletons of hadrosaurs and Triceratops that seemed to have survived initial attacks . Some researchers argue that if Tyrannosaurus were a scavenger , another dinosaur had to be the top predator in the Amerasian Upper Cretaceous . The top prey were the larger marginocephalians and ornithopods . The other tyrannosaurids share so many characteristics with Tyrannosaurus that only small dromaeosaurs remain as feasible top predators . In this light , scavenger hypothesis adherents have suggested that the size and power of tyrannosaurs allowed them to steal kills from smaller predators . Most paleontologists accept that Tyrannosaurus was both an active predator and a scavenger .
