FLAGSTAFF, Ariz., Sept. 27 (UPI) -- Paleontologists say fossils discovered in Arizona's Petrified Forest National Park are of an extinct reptile from a family of creatures never seen before.
The 3-foot-long crocodile-like reptiles, called Revueltosaurus callendari, were first thought to be plant-eating dinosaurs, but scientists soon determined they weren't, the (Flagstaff) Arizona Daily Sun reported Thursday.
