Velociraptor
🔊 /vəˌlɒsɪˈræptər/
is a genus of small dromaeosaurid dinosaur that lived in
Asia during the
Late Cretaceous epoch, about 75 million to 71 million
years ago. Velociraptor (commonly referred to as "raptor") is one of
the dinosaur genera most familiar to the general public due to its
prominent role in the Jurassic Park films 🎬. In real life, however,
Velociraptor was roughly the size of a turkey, considerably smaller
than the approximately 2 m (6.6 ft) tall and 90 kg (200 lb) reptiles
in the novels and films.
