FRANCE: Remains of a mutilated dinosaur victim provide strong evidence that T rex and his kin were violent animals and practiced cannibalism, scientists say.
A new study shows that the skull of a genus of tyrannosaur called Daspletosaurus suffered numerous injuries during life, at least some of which were likely inflicted by another Daspletosaurus.
It was also bitten after death in an apparent event of scavenging by another tyrannosaur. Thus there is evidence of combat between two large carnivores as well as one feeding on another after death, researchers said.
Daspletosaurus was a large carnivore that lived in Canada and was only a little smaller than its more famous cousin Tyrannosaurus. Like other tyrannosaurs it was most likely both an active predator and scavenger.
The individual in question, from Alberta Canada, was not fully grown and would be considered a ‘sub-adult’ in dinosaur terms.
It would have been just under six metres long and around 500 kg when it died.
Researchers found numerous injuries on the skull that occurred during life. Although not all of them can be attributed to bites, several are close in shape to the teeth of tyrannosaurs.
