Deinonychus

A fossilized Deinonychus antirrhopus skeleton. Like many museum skeletons, this might be replica of the original set of fossils.

Deinonychus was a small, bipedal, Cretaceous-era carnivorous dinosaur. It had a long, sickle-like claw on the end of its big toe. Deinonychus fossils were first discovered in 1931 by Barnum Brown in southern Montana. In 1964 the fossils were designated Deinonychus antirrhopus by John Ostrom and Grant Meyer.
