Biology:Navajosphenodon

Navajosphenodon is an extinct genus of sphenodontid reptile from the Early Jurassic Kayenta Formation of Arizona, United States. It is known from a fully articulated skull and skeleton (the holotype, MNA.V.12442) and several referred specimens, representing individuals of various ontogenetic stages. Navajosphenodon is similar in many aspects to the extant tuatara, both belonging to the Sphenodontinae, including sharing a complete lower temporal bar. It is one of the oldest known sphenodontines.
