The fossils discovered in Alberta, Canada, in 2010, allowed us to realize that it is a new species of tyrannosaurus, a close relative of Tyrannosaurus rex.
According to Live Science, the 79.5 million-year-old fossils discovered in Alberta, Canada in 2010, belong to a tyrannosaurus now named by the scientists of Thanatotheristes degrootorum.
The species now identified lived during the Cretaceous, a period between 145 million and 65 million years, and was an imposing creature. From the snout to the tail, the dinosaur was about eight meters long, was approximately two meters tall and had teeth more than seven centimeters.
Like other tyrannosaurs, the "reaper of death" ("Thanatos" is the Greek god of death and "theristes" means "reaper" in Greek) had strange bumps on his skull that gave him a monstrous appearance.
A new species of tyrannosaur has been discovered in Alberta, Canada. It measured 2.4 metres at the hip and was an apex predator 79 million years ago. It has been named Thanatotheristes degrootorum, meaning “reaper of death”.

But it also had a unique feature: a distinct set of vertical grooves that ran from the eyes along the upper snout (although scientists still don't quite know what its purpose was).
The only dinosaurs that had been found in this rock formation were herbivores – Xenoceratops foremostensis and Colepiocephale lambei – which suggests, according to Darla Zelenitsky, assistant professor of paleontology at the University of Calgary and one of the authors of the study published in the journal Cretaceous Research, which would be a good source of food for T. degrootorum.
According to scientists, this new tyrannosaurus is the oldest species ever found in North America and is also the first previously unknown tyrannosaurus species to be discovered in Canada in 50 years. Daspletosaurus had been the last to be discovered, in the year 1970.
