Description

Late Triassic

Bull Canyon Formation

Guadalupe County

New Mexico, USA

Fine 0.15 inch tooth.

Reptile, Archosaur.

Once considered an early ornithischian dinosaur based on isolated teeth, Revueltosaurus is now classified as a pseudosuchian archosaur which makes it more closely related to early crocodilians.  The reassignment is due to more complete remains, including skeletons, being found and studied.
