Utahraptor

Order: Saurischia · Suborder: Theropoda · Infraorder: Tetanurae · Family: Dromaeosauridae
Found in eastern Utah, this dinosaur was armed with a 15-inch(35-cm) claw on one toe of each hind foot, claws on each finger of its hands, and razor-sharp teeth. Believed to be an agile, very fast predator, Utahraptor probably attacked prey many times larger than itself, striking numerous fatal blows with its sharp hind claws. It is also believed to have hunted in packs, thus indicating behavior of a relatively intelligent and warm-blooded animal. Utahraptor combines the behavior of Velociraptor and Deinonychus with much greater size.
