T. Rex's early cousin, Moros Intrepidus, was not that powerful




(Newser)

The Tyrannosaurus Rex may have been the fiercest dinosaur on the planet just before the creatures disappeared, but even T-Rex had a modest start. A new fossil found in Utah shows that an earlier iteration of the behemoth stood only 3 feet to 4 feet tall and weighed about 170 pounds. A team led by a North Carolina Paleontologist, Lindsay Zano, called this version of Moros intrepidus, which means "a precursor to doom," CNN reported. The name is a nod to what the little being would develop in millions of years on the road. Moros lived about 96 million years ago, preceding the dinosaur we know as T-rex for 30 million years, and the discovery can help shed light on the comparatively scarce fossil record of this particular evolution.

"When and how fast the Tyrannosaurus went from King to Flower to Ball, it's been tough for paleontologists for a long time," says Zano in a news release. "The only way to attack this problem is to get out there and find out more about these rare animals." Not that Moros was full wallflower: open bones suggest it is extremely fast. "It was easy to cope with the prey, avoiding the confrontation with the best predators of the day," says Zano. At some point the Tyrannosaurs have displaced the giant allosaurus as a dinosaur-dominating world, but exactly when and why that happened remains mysterious, according to the Atlantic Ocean. Only newly discovered fossils can help shape the puzzle together, and Moros is seen as a key first step. (Read more stories about Tyrannosaurus rex.)
