Figure 3. A in Sculpture and vascularization of dermal bones, and the implications for the physiology of basal tetrapods

Figure 3. A, Zatrachys serratus (Temnospondyli, Zatracheidae), UCMP 34137. Posterior portion of the skull with radial and polygonal/tubercular sculpture. B, Lanthanosuchus watsoni (Parareptilia, Lanthanosuchidae), PIN 271/1. Posterior skull table with pronounced sculpture. C, Cochleosaurus bohemicus (Temnospondyli, Edopoidea), MB.Am.80, cast. The dermal sculpture is much subdued medial to the crest extending from the orbit to the snout. D, Vigilius wellesi (Stereospondyli, Brachyopoidea), ROM 23857, cast. Posterior portion of the skull, with sculptured bones (median part of the skull table) and bones that are largely smooth. E, Melosaurus uralensis (Stereospondylomorpha, Melosauridae), PIN 161/3. Symphysis in ventrolateral view. F, Gerrothorax pustuloglomeratus (Stereospondyli, Plagiosauridae), SMNS without number. Part of the mandible in labial view: whereas the angular is heavily sculptured, the dentary is only faintly striated. For abbreviations, see text.
