Velociraptor roamed the Earth about 85.8 million to 70.6 million years ago during the end of the Cretaceous Period.
In 1924, Henry Fairfield Osborn, then-president of the American Museum of Natural History, named Velociraptor. He bestowed the name on this dinosaur, which is derived from the Latin words "velox" (swift) and "raptor" (robber or plunderer), as an apt description of its agility and carnivorous diet.
Earlier that year, Osborn had called the dinosaur Ovoraptor djadochtari in an article in the popular press, but the creature wasn't formally described in the article and the name "Ovoraptor" wasn't mentioned in a scientific journal, making Velociraptor the accepted name.
A member of the Dromaeosauridae family of small- to medium-sized birdlike dinosaurs, Velociraptor was roughly the size of a small turkey and smaller than others in this family of dinosaurs, which included Deinonychus and Achillobator. Adult Velociraptors grew up to 6.8 feet (2 meters) long, 1.6 feet (0.5 meter) tall at the hip and weighed up to 33 lbs. (15 kilograms). Like Tyrannosaurus rex, Velociraptor had a prominent role in the "Jurassic Park" movies, but scientists do not believe it resembled anything close to its Hollywood depiction in terms of size or appearance. In fact, the movies' Velociraptor was actually modeled after Deinonychus, and sported a similar size and snout. While the Velociraptor was featherless in the movies, paleontologists discovered quill knobs (places where the flight-related feathers of birds are anchored to the bone) on a well-preserved Velociraptor forearm from Mongolia in 2007, indicating the dinosaur had feathers. Despite having feathers, however, the arms of Velociraptors were too short to allow them to fly or even glide. The find suggests that the dinosaurs' dromaeosaurid ancestors could fly at one point, but lost that ability, according to the studies published.
