New types of dinosaur found that “rewriting” the genealogical tree T.Rex

Scientists have discovered a new kind of dinosaur – in the collection of the Mongolian Museum – which is said to “rewriting” the evolutionary history of tyrannosaurus.

The researchers concluded that the two 86-year-old skeletons they studied belonged to the species, which is now the closest known ancestor of all tyrannural predators, which includes a iconic T.Rex.

Researchers have called the Hankhulu species (pronounced khan-li) mongoliensis, which means the Prince of the Dragon Mongolia.

Discovery, Published in nature, This is a window in the way the tyranasar developed to become powerful predators who terrorized North America and Asia until the end of the Dinosaurs’ reign.

“” Prince “refers to the fact that it is an early, smaller tyrannosuroid,” said Professor Darla Zelenitsky, a paleontologist at Calgary University in Canada. Tyrannosuroids are the super -family of predatory dinosaurs that went on two legs.

The first tyransaida, though they were tiny.

Jared Voris, a student-science student, who managed her studies with Professional Zelenitsky, explained: “These were these truly small predators who lived in the shadows of other Apex predatory dinosaurs.”

Khankhuulu is an evolutionary shift – from those small hunters that were cleared during the Jurassic period – to the formidable giants, including T -REX.

It would weigh about 750 kg, while the adult T.Rex could weigh up to eight times, so “it is transitional (fossil),” Prof. explained. Zelenitsky, “between previous ancestors and powerful tyranosaries”.

“It helped us to review the tyrannosaurus family tree and rewrite what we know about the evolution of the tyranasers,” she added.

The new species also shows the early evolutionary stages of the features that were key to tyrannal tyrannant, including the anatomy of the skull, which gave her a strong jaw. Jared Voris explained: “We see the features in the nasal bone, which eventually gave tyranasar, who are very powerful bite forces.”

The evolution of such powerful jaws allowed T-Rex to pounce on great prey and even bite the bones.

The two partial skeletons, which the team considered in this study, were first discovered in Mongolia in the early 1970s. Initially, they were intended for the existing species known as Alectrosaurus, but when Mr. Voris examined them, he identified functions similar to the tyrannosaurus that distinguished it.

“I remember getting the text from him – that he thought it was a new species,” Professor Zelenitsky reminded.

The fact that this group of dinosaurs was able to move between North America and Asia – through the land bridges, which at the time connected Siberia and Alaska – also helped them find and occupy different niches.

Mr. Voris explained: “This movement back and forth between the continents mostly pushed the evolution of different tyrannural groups” for millions of years.

Professor Zelinitsky added: “This discovery shows us that before the tyrannosaura became kings, they were princes.”
