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.
