A tiny tyrannosaur
When you think of Tyrannosaurus rex, a small set of striking physical traits comes to mind: an oversized skull with powerful jaws, tiny forearms and the muscular hind legs of a runner. But, researchers have just unearthed a much smaller tyrannosauroid in China, no more than three meters long, that displays all the same features -- and it predates the T. rex by tens of millions of years.

Tiny T-rex started the trend of terrifying traits
When you think of Tyrannosaurus rex, you probably imagine the unique physical traits that defined the species: a large skull and tiny forearms attached to a tremendous body. But, the Sept. 18 issue of Science reports that researchers have just unearthed a much smaller tyrannosaurid in China, no more than three meters tall, that displays all the same features -- and predates the T. rex by tens of millions of years.
