The fossil remains of one were found with a Protoceratops, as they had killed each other in battle.  
Like other Dromaeosaurids, it had a large brain for its body size, and it inhabited hot, dry ecosystems about 80 million years ago during the late Cretaceous period. The fossil remains of one were found with a Protoceratops, as they had killed each other in battle.  There is only one recognized species of it, V. mongoliensis, named for its discovery in central Asia.  About two meters long, current theory suggests it may have been covered with feathers, and it had a sickle-like, 9 centimeter retractable claw on the middle toe of each foot.  A bipedal dinosaur that may have hunted in packs with a name meaning "swift robber," FTP identify this dinosaur made famous by Michael Crichton's Jurassic Park.
