Diagnosis
ReferenceDiagnosis
E. D. Cope 1870Elements of the limbs, of the pes and manus differentiated, in definiitenumber. "Postorbitals and supratemporals " of Owen wanting. Quadratum immoveably united by suture with opisthotic, prootic and quadratojugal. Sacrum of from one to six vertebrae.
Neural arches attached by suture in most. Premaxillary divided. Cranial walls cartilaginous anteriorly. Palatine bones in contact with maxilliaries, and united by suture with them.
Circulatory System (known only in the Crocodilia). Heart with complete septum of the ventricles; a communication between aorta roots.
Nervous System (known only in the Crocodilia). Cerebellum with small lateral lobes and weak plicae.
S. J. Nesbitt 2011The least inclusive clade containing Crocodylus niloticus Laurenti, 1768, and Passer domesticus Linnaeus, 1758 (sensu Sereno, 2005).
