WASHINGTON: A new study in Canada has shown that tyrannosaurs, the family in which the fearsome Tyrannosaurus rex belongs to, may have indulged in a bit of cannibalism.
Researchers studied the skull of a Daspletosaurus and discovered numerous injuries inflicted during its life and death. A genus of tyrranosaur, the Daspletosaurus, is smaller than the T. rex but still, the dinosaur the skull belonged to was believed to be under 20 feet long and over 1,000 pounds in weight. However, a Daspletosaurus of that size is just a sub-adult (an older teen, in human terms).
An examination of the Daspletosaurus’ skull revealed that the dinosaur sustained injuries throughout its life. While not all are attributed to bites, several closely resemble the tyrannosaurs’ teeth. One specific bite was discovered at the back of the head, breaking off a part of the skull and leaving a circular puncture on the bone resembling a tooth. Alterations could be observed on the surface of the bone which meant the Daspletosaurus healed from its injuries.
David Hone, from the Queen Mary, University of London and lead author for the study, said that the dinosaur clearly had a tough life.
