Alberta is a tyrannosaur graveyard. There rest fantastic carnivores of the Cretaceous, such as Albertosaurus, Gorgosaurus, Daspletosaurus and, of study course, Tyrannosaurus rex.

Now, paleontologists in the province have announced the discovery of Canada’s oldest acknowledged tyrannosaur: Thanatotheristes degrootorum, or “the Reaper of Death.”

With its razor-sharp teeth and formidable two-ton body, the freshly found out species terrorized the location some 79.5 million many years back. Nevertheless smaller than T. rex, it continue to calculated about 30 toes lengthy and about 8 feet tall. The new species was at least 2.5 million a long time older than its closest relatives, which may give insight into when tyrannosaurs grew from small carnivores into the apex predators that perished 66 million years back.

“Prior to the discovery, we understood all the most well-known tyrannosaurs like T. rex, Albertosaurus, Gorgosaurus, have been all coming from the previous 10 or so million years of the Cretaceous,” reported François Therrien, a paleontologist at the Royal Tyrrell Museum of Palaeontology in Drumheller, Alberta, and an creator on the paper. “Now, with the new species we have in fact pushed back the file of tyrannosaurs.”
