Wishbone bolsters dinosaurs' link to birds

The possibility that birds evolved from dinosaurs was bolstered by the identification of a wishbone in a velociraptor skeleton.

Wishbones already had been found in some other meat-eating dinosaurs. The wishbone of the velociraptor showed up in a specimen found in 1991 in Mongolia, researchers from the American Museum of Natural History in New York and George Washington University in Washington reported in Thursday's issue of the journal Nature.Velociraptor, a 6-foot-long hunter that ran on its hind legs, is a member of a dinosaur group thought to be the most closely related to living birds.

Velociraptor was a star of the movie "Jurassic Park."
