Canada’s latest tyrannosaur has been named a “refugee in death”

Canada's latest tyrannosaur has been named a "refugee in death"

Alberta is an oppressive cemetery. There is a great muscular rest of the Cretaceous Albertosaurus, Gorgosaurus, Despletosaurus and, of course, Tyrannosaurus Rex.

Now, archaeologists in the province have announced the discovery of Canada’s oldest Tyrannosaur: Thanatotheritis degroatorium, or “deadly absorber”.

The newly discovered species, with its razor-sharp teeth and two-toned frame, terrified the region some 79.5 million years ago. T Although smaller than Rex, it still measures about 30 feet tall and 8 feet tall. The new species was at least two and a half million years older than its nearest relatives, which could be traced back to the predecessor who died from predatory atrocities, from small carnivores to predators.

“Prior to the discovery, we knew that famous terrorists like T-Rex, Albertosaurus, Gorgosaurus all came from the last ten or three million years of the Cretaceous,” said Francois Therion, a paleontologist Author of the Royal Tyrrell Museum of Paleontology and a paper on Drumheller, Alberta. “Now, with the new species, we have actually pushed the oppressive record back.”

The finding was published in the journal in January Cretaceous Research, Based on the bones discovered by a pair of paleo-enthusiasts.

Sandra and John De Groot walked along the shores of southern Alberta in the 21st where the Oldman River merged with the Bow River. They put some stains on the ice.

“We looked down and I jokingly said,” Hey it looks like a dinosaur jaw! “” Said Mr. de Groot. When she bent over to catch it, her heart started to throb. “We looked around a bit and that was definitely it.”

The couple, who owns a farm in nearby Hayes, had previously collected ammonite and miniature bones while walking through Shortgrass Prairie. However, they have not made such exciting discoveries before.

“It was one of those ‘wow’ moments of the ‘holy cow!’ You got some teeth lying on the ground here, “said Mrs de Groot. They found three large brown parts of a dinosaur jaw.

Two years later, Donald Henderson, an old expert At the museum, gave a lecture at the school where Mrs. de Groot is an alternative teacher

“I said” Oh hey, we have a jaw in the house, you should come see it, “” said Mrs. de Groot. “And he said ‘What ?!'”

De Grotes donated the specimen to the museum and, along with a team of physicians, went to the river and discovered more openings. Scientists knew that it was a tyrant, but not the kind.

For almost a decade, the bones have been sitting in a storage drawer Graduate student Jared Voris is a student At the University of Calgary, they began their experiment. The long and deep smoke was in association with another oppressive group called Daspletosaurus, suggesting that the two were in a close relationship. He also noticed the fun vertical vertices lined with the dinosaur’s upper jaw, in addition to the war spots on his face.

“The raids were things we had never seen before in a brutal accident, especially not in Alberta’s other tyrannical heroes,” he said.

Mr Voris also observed other features that set Tyrannosaur apart from its relatives, such as its oval-shaped cheeks and the sides of its skull. These differences, along with the oppressive old age, led the team to classify it as a new species, for which they honored De Groot, and also as a new genus originally named for the Grim Reaper. It’s just a coincidence that it shares names with Thanos and Groot in the Marvel Cinematic Universe.

Lindsey Janno, an old expert From North Carolina State University involved in the study, he said the pronounced shikas were “worrisome.”

“Despite its awfulness, it is an important new animal that borders on a worrying gap in the tyrannical fossil record,” said Dr. Janno. Janno said.

However, some archaeologists have taken the issue by referring to it as a distinct genus.

Thomas Carr, an old expert At Carthage College in Wisconsin, he agreed that the specimen had enough unique properties to call it a new species, but he preferred the “Despletosaurus digiogram.”

Dr. Carr says, “The name of a new genus struck me as unnecessary since the fossil became almost identical with that of its nearest relative, Dyspletosaurus.

One of the co-authors of the paper, Darla Zelenitsky, an old expert At the University of Calgary, defending the classification, the oppressor confirmed the new name on Nasir’s upper jaws and its individual cheeks.

“Because of all the differences we have found, it is very difficult for us to justify this animal as a national species of Daspletosaurus,” he said. He added that as the team unveiled more samples, they would likely find more differences between Thanatoristes deGiogram and other oppressors.

Enough to hold Ritter’s name in his grave forever
