Not so awful as the whole! T-rex began as a great cocoa dinosaur

Scientists have discovered T-rex mini-me who was the ancient emperor of the tyrant dinosaurs.

The eating of small but small meat was the size of modern sea deer native to western North America, up to four feet and weighed about 180 pounds.

When he lived 97 million years ago, he was not at the top of the food chain, as all the great archaeologists were predators.

But the fossil discovery fills the gap of 70 million years in the fossil records that link an early tyrannosaur to the world famous T-rex.

How and when tyrannosaurs were replaced by the diners and how his string became a scientific mystery.

The great new founder tyrannosaur lived close to the end of the greatest elites and evolutionary beginnings of the greatest lizard's killer of the Earth.

Because of this, the names have been named Moros intrepidus – "harbinger of doom."

It was a key to how T-rex got into force, says paleontologist.

The fossils were found in Utah today when the area was a colorful, delite environment during the Cretaceous period.

Assistant Professor of Research Dr Lindsay Zanno at North Carolina State University said: "With a deadly combination of bone spray forces, stereoscopic vision, rapidly growing rates, and colored size, tyrant dinosaurs defeat disagreement for 15 million from years leading to the end – Crisisian displacement – but it was not always so

"Early in their turn, tyrannosaurs were healed in the shades of archaeic strings such as those who had already set up at the top of the food chain."

The leading author and the head of paleontology at the North Carolina Museum of Sciences added mid-state, primitive tyrannosaurs in North America dating from Jurassic (about 150 million years ago).

By the Cretaceous – about 81 million years ago – North America tyrannosaurs have become a huge, iconic predators that we know and love them.

Yet, the fossil record between these periods has been empty slate, preventing scientists from collecting the story behind tyrannosaurs in North America.

Professor Zanno said: "When and how fast tyrannosaurs go from wall flowers to the king of the prom, paleontologists have been tired for a long time.

"The only way to attack this problem was to go out and find more data on these rare animals."

A decade looking for incredible teeth and backbone of the new tyrannosaur inrocks deposited at the dawn of the Late Cretaceous.

The lower bones of the Moros were discovered in the same area where she had already discovered Siats meekerorum, a carcharodontosaur who eats meat that lives during the same period.

Morries would have been over seven years of age and was almost full when she died and stood only three or four feet high in the hip, for how much modern honey deer.

Professor Zanno added: "Moros was lightweight and extremely fast.

"These adaptations, together with advanced sensory abilities, are a sign of a wonderful predator.

"It could be easy to prey, while avoiding conflicts with the predators of the day.

"Although the earliest Cretaceous tyrannosaurs were small, their prey adverts meant they were exhausted to take advantage of new opportunities in warming up temperatures, raising sea level restructuring ecosystems and extending the raids at the beginning of the Cretaceous Late.

"We now know that it has taken less than 15 million years to get into force."

Moros bones also revealed the origin of T. rex's string on the North American continent.

When the Moros scientists gave a family tree to a tyrannosawr, they knew that belonging to Asia was their nearest relatives and crossed the Alaskan land bridge.

Professor Zanno said: "T. rex and famous peers such as Triceratops may be among our most beloved cultural icons, but we have to exist to incredible ancestors who emigrated here from Asia at least 30 million years ago.

"Moros is a sign of establishing Late Cretaceous iconic ecosystems of North America."

The study was published in the Communication Biology magazine.
