Tyrannosaurus Rex may have been a cannibal, 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 resulted from the dinosaurs being eaten rather than being caused during fighting, they claim.
Dr Nick Longrich, from Yale University in Connecticut, made the discovery after finding a 65-million-year-old dinosaur fossil with unusually large bite marks. Given the age and location of the bone, from western North America, the marks could only have been made by T. Rex, he reports in the journal PLoS ONE.Reuse content
