Raptorex: T-Rex Ancestor Weighed As Much As A Man

A 9-foot dinosaur excavated illegally from northeastern China and purchased by a private collector who brought it to the attention of paleontologists (hey, they'll return it after they're done) is about the same weight as a grown human yet had still evolved all the hallmark anatomical features of Tyrannosaurus rex - except 30 million years earlier, according to a study in Science.

Raptorex displays the hallmarks of its famous descendant, Tyrannosaurus rex, like an oversized head, tiny arms and feet well-suited for running. The Raptorex brain cast also shows enlarged olfactory bulbs, like T. rex, indicating a highly developed sense of smell.

My friend and I are planning to have a China tour this October, so this is really interesting news. http://www.ritztours.com offers really affordable China tour travels. We are looking forward to seeing this when we visit China.

I think they would have been fun to hunt, hopefully not ending like the hunter in Jurassic Park.
