A New Reptile from the Richards Spur Locality, Oklahoma, U.S.A., and Patterns of Early Permian Parareptile Diversification

摘要: ABSTRACTThe Lower Permian Richards Spur locality is the most speciose Paleozoic continental vertebrate assemblage currently known, and a significant proportion of tetrapod diversity found at made up parareptiles. The first parareptile to be described was Colobomycter pholeter. It has been characterized by its enlarged premaxillary tooth paired maxillary teeth, unique dentition that grants it an appearance quite distinct from other parareptiles Spur. Here we describe new cranial material referable Colobomycter. This differs C. pholeter in possesses least three more teeth on maxilla, are gracile than those pholeter, lacrimal restricted externally orbital margin does not exhibit extra lateral exposure. We infer these differences merit specific distinction assign fossil Colobomy...
