- Notes: 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 itshands, 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 alsobelieved to have hunted in packs, thus indicating behavior of a relativelyintelligent and warm-blooded animal. Utahraptor combines the behaviorof Velociraptor and Deinonychus with much greater size.
