Imagine a giant predator as big as Tyrannosaurus  rex that had powerful 8-foot-long arms armed with 10-inch-long claws. Then make it the fastest dinosaur that ever lived and you would have Deinocheirus!

A stunning and fascinating discovery, Deinocheirus is only known from a single skeleton that contained only the arms and a few vertebrae and ribs. The information we do have indicates that Deinocheirus was a large and powerful two-legged predator that would have certainly used its massive arms to catch and kill its prey. If Deinocheirus was in fact a very large member of the Ornithomimosaurian family as scientists now believe (see Gallimimus  ), it could have been very fast - maybe the fastest dinosaur that ever lived.
