Velociraptor ("fast hunter") is the name for a small, fast-running, carnivorous dinosaur. Velociraptor was small for a dromaeosaurid, with adults measuring up to 1.8 meters (5.9 ft) long, 0.62 meters (2 ft) high at the hip, and weighing 20 kilograms (45 lb)[1] The velociraptor is extinct and is thought to have existed between 99 and 65 million years ago, in the late Cretaceous.[2]
The first Velociraptor fossil was found in Mongolia in the 1920s by an American Museum of Natural History expedition, and a number of fossils have been found since then in Mongolia and northern China. The most well-known find, discovered in 1971, includes a complete Velociraptor skeleton wrapped around that of a Protoceratops, an early ceratopsian and ancestor of Triceratops. The two were apparently in mid-fight when they were buried.[3]
Did it have feathers?
"The researchers believe the bumps on the arm bone are remnants of quill knobs, places where the quills of secondary feathers — important for flight in many modern birds — were anchored to the bone." [1]
Stephen Spielberg's Jurassic Park
The Velociraptor played a prominent part in Stephen Spielberg's motion picture Jurassic Park in which it was misrepresented as a much larger creature. It was in fact merely the size of a turkey.[4] The version of the Velociraptor in Jurassic Park more closely resembled a Deinonychus, a close relative of Velociraptor.
