Multimedia - Paleontology at Petrified Forest National Park: Revueltosaurus callenderi

In 2004 at Petrified Forest National Park paleontologist Bill Parker discovered a graveyard, or quarry, of the bones of a crocodile-like creature that lived about 215 million years ago. In 2006 he found the first nearly complete Revueltosaurus callenderi skeleton. By 2012 they had found eleven individuals, including one well-preserved skeleton that provided some of the previously missing pieces.
