Velociraptor

Velociraptor is one of the best-known dinosaurs, made popular by the JP movie franchise. The films featured this dinosaur as a killing machine, armed with ripping jaws and powerful claws; JPIII in particular made velociraptors social animals akin to modern wild dogs or spotted hyenas, able to coordinate their attacks as a pack and to communicate (one way) with the human characters.

Sadly, the movie depiction of velociraptors is incorrect: these dinosaurs were much smaller than the modern humans are, and probably were much more feathered than even in JPIII. It is equally unknown if they were pack hunters or not. In their own econiche, however, velociraptors were very formidable predators; the famous 'fighting dinosaurs' fossil has preserved a velociraptor fighting another dinosaur, a protoceratops. This was further developed in "The Truth about Killer Dinosaurs" duology, where the velociraptors were studied in detail, including their hunting and killing of protoceratops; especial attention was given to the killing claw, which was shown to be a stabbing, not a slicing weapon - a fact that was never developed further by dinosaur specialists.

Velociraptor lived in Asia, during the late Cretaceous, and it died out about 70 MYA, some time before the K-T extinction for reasons unknown.
