A new species of Tyrannosaurus is discovered and named 'Reaper'

The only dinosaur known as a species of the genus Tyrannosaurus is `` Tyrannosaurus rex '', but on February 10, 2020, as a new species belonging to the Tyrannosaurus family, a fossil of a dinosaur with the scientific name `` Thanatotheristes degrootorum '' Was found. This new dinosaur was called the religious god of death ' Thanatos ' in Greek mythology because it seems to have reigned at the top of the ecological pyramid at the same time.

Researchers at the University of Calgary and the Royal Tyrrell Museum of Paleontology have published the latest research on Cretaceous dinosaurs. Dr. François Serien, a dinosaur and paleoecology scholar at the Royal Tyrrell Paleontological Museum who worked on the study, said, `` The death of a tyrannosaurus discovered in Canada as the first new species in 50 years. '' I am pleased to find a new species of Tyrannosaurus called.

The most recent tyrannosaurus found in Canada was the

Daspretsaurus , discovered in 1970. Although Daspletosaurus is a tyrannosaurus dinosaur, it is classified as a species of the genus Daspletosaurus.

By analyzing a new species of fossils found in Alberta, Canada, the research group has concluded that fossils are part of the skull of a new species of dinosaur. `` Thanatotheristes degrootorum has many features on the skull, the most prominent of which is the longitudinal ridge running along the long upper jaw, '' said Jared Voris of the University of Calgary, who participated in the study. .

According to the research team, Thanatotheristes degrootorum is a dinosaur about 79.5 million years ago, and it was estimated that it lived 2.5 million years before its closely related Tyrannosaurus Rex. So far tyrannosauridae of dinosaurs that have been discovered in Canada, daspletosaurus,

gorgosaurus , Albertosaurus was, and Tyrannosaurus Rex only.

In addition, in Alberta, Canada, where the fossil of Thanatotheristes degrootorum was found, it has been revealed that dinosaur fossils found in the past were from 77 million to 66 million years ago. In addition, the dinosaur is estimated to have been living in Alberta in Thanatotheristes degrootorum the same period Korepiokefare and Zeno Keratopusu from that only, research team and Thanatotheristes degrootorum had reigned at the top of the ecological pyramid at the same time the analysis want did.

Since it had been an apex predator, new species of dinosaur is the Grim Reaper of Greek mythology as 'Thanatos (Thanatos)', 'means a person to harvest Thersites from (Thersites)', was named 'Thanatotheristes'. The name 'degrootorum' in the latter half of the name is derived from the name of the fossil discoverer John de Groot.

Groot, a farmer, found a fossil fragment of Thanatotheristes degrootorum while hiking in Hays, Alberta. 'The fossil of the jawbone was a really wonderful discovery, and I could quickly see that it was special because I could see the fossilized teeth clearly,' said Groot.

Groot, a fossil discoverer. He and his family support paleontological fieldwork in southern Alberta.

'I was told that John would someday find a dinosaur fossil, so the discovery of jaw bone fossils was very exciting,' said Andorra de Groot, wife of John de Groot. On the contrary, it is unbelievable that the fossils we discovered were of a new species and that our surnames were given to the names. '

Dr. Serien, who participated in the study, said, `` This discovery is important to bridge the gap for understanding the evolution of Tyrannosaurus, '' Tyrannosaurus is more diverse in Cretaceous Alberta than previously thought. Pointed out.
