(Newser) – The dinos depicted in Jurassic Park really were big and nasty and hunted in packs, and fossilized footprints show where they did it: in China, about 100 millions ago. Standing 1.2 meters tall at the hip, the dromeosaurs ran in packs of six and held up big killing claws—just like in the movie. They weighed about 200 pounds, experts say, like a big cougar or jaguar.

But they weren't Velociraptors, dinos that grew only to turkey-size. Until today's update, the closest dino to Spielberg's predators were Utahraptors, but they didn't move in packs or raise that terrible claw. Scientists had thought large raptors once roamed Asia, but today's report is the first to prove it, reports NewScientist.
