Velociraptor means "fast thief." This fast-running dinosaur, which lived during the late Cretaceous period (about 85-80 million years ago), has become quite popular due the movie Jurassic Park. Standing only about 3 feet tall (and 5 to 6 feet long), Velociraptors were much smaller than depicted in the movie. They were, however, fierce predators, and their sickle-shaped talons could reach the length of the teeth on sabertooth cats, making them a formidable adversary. As a result of their Hollywood exposure, they have become popularly known as "raptors", a name which also refers to other dromaeosaurids.
