Newfound Raptorex kriegsteini (illustrated above) resembled T. rex in nearly every way, except size, scientists announced in September 2009.

The new dinosaur species lived millions of years before its infamous descendant, and Raptorex's discovery suggests that tyrannosaurs' stumpy arms evolved later than previously thought.
