Large bite marks on bones suggest T rex was cannibal

DINOSAUR king Tyrannosaurus rex may have been a cannibal that preyed on its own kind, new evidence suggests.

Large bite marks on T rex bones could only have come from other members of the same species, say scientists. The gouges are clearly the result of feeding, not fighting, say the researchers.

US scientist Dr Nick Longrich made the discovery after finding 65 million-year-old dinosaur fossil with unusually large bite marks.
