   Only in the Chelonia (Fig. 32 b) are the prevomers single, though sometimes fused in the Rhiptoglossa, Theropoda, and Theriodontia (Figs. 43 c, 44 e). They are edentulous in all known reptiles except the Cotylosauria (Fig. 6), some Theromorpha, perhaps, certain "Pseudosuchia," Diaptosauria (Fig. 63), and Squamata. Posteriorly in the Squamata (Figs. 55 c, 56 b) they articulate with the palatines only, as also in some Chelonia (Figs. 31 a, 32 b) and Plesiosauria (Fig. 46 b). Generally believed not to represent the unpaired vomer of the mammals.
