The fossils of a newly discovered T. rex cousin — a vicious, meat-eating dinosaur with serrated teeth and a monstrous face that scientists are calling the 'reaper of death,' has been discovered in Alberta, Canada.
"These [features] differ from tyrannosaur groups in other regions: the more lightly built relatives, like, that tended to live slightly farther north in south-central Alberta, and more primitive forms with shorter, bulldog-like faces of the southern USA, [including] New Mexico and Utah," Zelenitsky said.
It's unclear why these tyrannosaurs had such different body types and head shapes, but it could be due to differences in diet — that is, the type of prey they ate and their strategy for hunting them, Zelenitsky said.-like tyrannosaurs were diversifying in the northern part of western North America about 80 million years ago, said Steve Brusatte, a paleontologist at the University of Edinburgh in Scotland, who wasn't involved in the study.
"This seems to be a bigger theme: There were different subgroups of tyrannosaurs characteristic of certain times and places, and they did not all mix together," Brusatte told Live Science.
