clipped from: www.newscientist.com Jurassic Park had the right ideas about "raptor" dinosaurs – they were big, they were bad, and they roamed in packs – at least when they lived in Shandong Province, China, 120 to 100 million years ago, a fossil trackway shows. It is the first solid evidence of group behaviour among the speedy two-legged predators.
The movie depicted Velociraptor as a cunning and deadly predator of near-human size, in fact much larger than the real turkey-sized Velociraptor. Palaeontologists later found a much larger related dinosaur called Utahraptor in Utah, which is on the same scale as the movie raptor.
There had been no evidence of pack hunting, however, or that the dinosaurs had lifted the deadly-looking specialised claw found on one toe of each foot to keep it from wearing on the ground, another behaviour shown in the movie.
