Anyone who finds a fossil should leave it where it is, note its exact location and contact the museum, he said.
He is looking at all the tyrannosaur bones to learn more about the evolution of the species.
Alberta's rugged and bare landscape has made it one of the top five places in the world for dinosaur fossils. By analyzing these bones, the paleontologists were able to identify several unique features, such as prominent vertical ridges running along the length of the upper jaw, enabling them to confirm the specimen as a new species.
"Exactly what the ridges do, we're not quite sure", Voris said.More news: Barcelona star Ousmane Dembele out for six months
The second part of the dinosaur's name pays tribute to De Groot.
According to the Royal Tyrrell Museum of Palaeontology, fossil skull fragments of the tyrannosaur, Thanatotheristes degrootorum, were discovered by a farmer and paleontology enthusiast in the southern part of the province of Alberta while he was hiking near Hays, about 150 miles southeast of Calgary. "We knew it was special because you could clearly see the fossilized teeth".
The University of Calgary student wasn't on a remote archaeological dig.
It's not believed to be a direct ancestor of T. rex.
When they lived, tyrannosaurs (including the Tyrannosaurus rex) were large predatory theropod dinosaurs. All three species form a newly named group of dinosaurs called Daspletosaurini.More news: Macaulay Culkin defends Michael Jackson in Esquire cover story

"So we went to the site and measured the stratigraphic section to describe the rock record where the specimen is from in order to determine the age of what that specimen was", said Therrien.
A new species of tyrannosaur that stalked North America around 80 million years ago has been discovered by scientists in Canada.
According to the team, T. degrootorum is one of the oldest tyrannosaur species ever discovered in North America and is at least 2.5 million years older than its closest relative.
Thanatotheristes provides scientists with insights into the tyrannosaur family tree and shows that tyrannosaurs from the cretaceous of Alberta were more diverse than previously known.More news: In Images: Rare snowfall carpets Iraq
"There are very few species of tyrannosaurids, relatively speaking", said Zelenitsky, co-author of the study that appeared in the journal Cretaceous Research.
