It appears the stars of Jurassic Park should have been decked out in feathers.
Alan Turner, of the American Museum of Natural History led a new study of a velociraptor forelimb found in 1998 which discovered quill knobs - which anchor feathers on modern birds - on the fossilized bone. “Finding quill knobs on velociraptor, though, means that it definitely had feathers." Turner said. "This is something we’d long suspected but no one had been able to prove.” The link above includes a really cool - and scary - illustration.
