A new source of tyrannosaur has been discovered in Utah – and he is small compared to his more known relative, T. rex.
Meet Moros intrepidus, a little tyrannosaurus, who lived in the Emera County in Utah. At 96 million years old is the oldest type of tiranosaurus chalk still found in North America. The find has reduced the 70 million year gap in the tyrannical dinosaur record.
And from the little ones, think about the size of deer mule. Moros was only three or four feet tall on the thigh. The sample found is more than seven years old and almost complete. This name means "the forerunner of doom". While the average primitive tyrannosaures have been found in North America since the Jurassic period (about 1
"When and how fast the tyrannosaurus have gone from the color of the ceremonial king for a long time, they have bothered the paleontologists," Zano says in a press release. "The only way we can attack this problem is to find out more about these rare animals."
Zano and her team spent a decade in hunting for dinosaur bones in the chalk of the late chalk. Their search finally led to teeth and hind limb by Moros. Zanno describes Moros as light and extremely fast.
"These adaptations, along with advanced sensor capabilities, are the mark of a great predator," Zanno said. "It can easily break the prey by avoiding confrontation with the top
The discovery of Moros causes paleontologists to believe that T. rex has benefited from warming temperatures and sea level rise at the end of the Cretaceous period  Zano said: "Now we know it is necessary to rise to power in less than 15 million years."
