Scientists say massive new dinosaur found in Utah is relative of T. rex

A newly discovered dinosaur is a relative of T-rex.

You think Tyrannosaurus-rex is old. Wait until you meet his great uncle. That’s right; paleontologists have discovered a new dinosaur that is an ancestor to T-rex. They unveiled the new dinosaur named Lythronax argestes on Wednesday in Utah.

The first part of the name means “king of gore,” an apt—if melodramatic—name to the ancestor to the “Tyrant Lizard,” T-rex. The fossil was discovered in Utah in 2009, indicating a half-pint version of tyrannosaurus at about 24 feet long and 8 feet tall at the hip.

Scientists believe Lythronax was alive in the late Cretaceous Period about 80 million years ago. He would have lived on a piece of land in a flooded North America. The findings bring the existence of giant dinosaurs 10 million years earlier than previously believed.

“We’re really changing the view of dinosaurs,” he told FoxNews.com. One misnomer, thanks to the famous, though inaccurate, film “Jurassic Park,” is that dinosaurs have poor eyesight. If the characters stood still, the giant dinosaur never saw them.

However, according to the researchers, the Lythronax had a very narrow snout with a wide back to its scull, suggesting forward-facing eyes with binocular vision, just like humans and other predators. Lythronax could see its prey very well.

“They were likely more creepy and fearsome,” said Imis.

A second major eye opener for most people is that Lythronax most likely had feathers, a soft-to-the-touch down (like what we have in our pillows).

“Based on fossils found elsewhere, we now that a lot of tyrannosaurs had something of a downy covering—protofeathers,” Irmis noted. “Dinosaur down probably would have been pretty comfortable as well,” he said.

The “king of gore” was discovered Grand Staircase-Escalante National Monument, where paleontologists spent the next four years digging up the fossils and sending them around the world to confirm they did belong to a new species.

The findings are being published in the journal PLOS One, and the information will provide valuable insight into how tyrannosaurus evolved through history. The researchers believe, for example, that the tyrannosaurus goes as far back as all the other giant predators. Their skulls—with the forward eyes and full row of sharp teeth—indicate as much.

“That skull is designed for grabbing something, shaking it to death and tearing it apart,” said Mark Loewen, a University of Utah paleontologist who co-authored the journal article. When asked what the Lythronax most likely ate, Loewen answered: “Whatever it wants.”
