New types of dinosaurs discovered that “rewriting” the T.Rex family tree

Scientists have discovered a new type of dinosaurs – in the Mongolian Museum group – they say “they repeat” the evolutionary history of the Tirinosaurs.

The researchers concluded that two 86-year-old skeletons that they studied belong to a type that is now the closest predecessor known to all Tyrannosaors-the collection of predators that include the famous T.Rex.

The researchers named Khankhuulu (clear Khan Ko-l), which means the Emir of the dragon from Mongolia.

Discovery, It was published in nature, It is a window on how Tyrannosaurss developed into the strong predators that have extracted North America and Asia until the end of the era of dinosaurs.

Professor Darla Zellingski, the world of cases from Calgary University in Canada, explained: “The prince indicates that this matter is early and smaller.

The first tyrannosauroids although small.

“These small predators with small feet that lived in the shadows of other predators,” said PhD student Jared Fores, who led the research with Professor Zelintsky.

Khankhuuluu represents an advanced transformation – of these young fishermen who were wandering during the Jurassic period – to the huge giants, including T -RX.

It was possible to weigh about 750 kg, while the adult adult could weigh up to eight times, so “this is a transitional (fossil) matter,” Professor Zelintsky explained, “between the previous grandparents and the great Tyrannosaurs.”

She added, “This helped to review the Tyrannosaur family tree and rewrite what we know about the development of Tyrannosaurs.”

The new species also shows early evolutionary stages of features that were the tyrannosaurs tyranny key, including the anatomy of the skull that gave them a strong jaw. “We see features in the nose bone, which eventually gave Tyrannosaurs, the strong sting power,” said Jared Fores.

The development of such a powerful jaws allowed to pounce on larger prey, and even bone through bones.

The partial skeletons that the team examined in this study were discovered for the first time in Mongolia in the early 1970s. They were initially appointed to an existing type, known as Alectrosaurus, but when Mr. Voris examined it, select the features that resemble the Tyrannosaur that distinguishes it.

“I remember getting a text from him – he thinks this was a new type,” Professor Zellingski recalls.

The fact that this group of dinosaurs managed to move between North America and Asia – through the bridges of the earth that connects Siberia and Alaska at the time – also helped them find different outlets.

Mr. Voris explained: “This movement is back and forth among continents mainly prompted the development of different Tyrannosaur groups” over millions of years.

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