Spielberg's name was briefly considered for naming of the new dinosaur. In reality, "Velociraptor", like many other maniraptoran theropods, was covered in feathers. Velociraptor Velociraptor (; meaning "swift seizer" in Latin) is a genus of dromaeosaurid theropod dinosaur that lived approximately 75 to 71 million years ago during the latter part of the Cretaceous Period. Two species are currently recognized, although others have been assigned in

If so, it would be the only known four-legged meat-eater among dinosaurs. Later paleontologists have not agreed with Dong's original assessment. They think this dinosaur walked on its hind legs as other theropods did, pronation of the lower arm being impossible. The strong arms could instead have been useful in catching prey. Assigned by Dong to the Megalosauridae, "Xuanhanosaurus" was found by Roger Benson in 2009 to
