Category:Neodiapsids

Articles relating to the Neodiapsida, a clade, or major branch, of the reptilian family tree. It includes all diapsids apart from some early primitive types, known as the araeoscelidians. In phylogenetic systematics, they are variously defined as the common ancestor and all its descendants of Younginiforms and "crown diapsids" (the common ancestor of lizards, crocodilians and birds, and all their descendants) [Callaway 1997], or all diapsids that are more closely related to Sauria than to Araeoscelidia (Laurin and Gauthier 2000).
