| Abstract: | "A new individual of Acroplous vorax is described and its systematic position within the Saurerpetonidae is reexamined. The new specimen is clearly conspecific with the type as shown by the narrow midline elements, broad supratemporal and intertemporal, wide but short lacrimal, and nearly identical pterygoids. The new specimen offers more data on the braincase, pterygoid occiput, lower jaw, and humerus. The internal process of the pterygoid is small and a well-developed epipterygoid caps the dorsal process of the pterygoid, indicating a more primitive basal articulation than that interpreted for Isodectes. Unfortunately, the condition in Saurerpeton is unknown for comparison. Like all other saurerpetonid genera (Dvinosuarus, Saurerpeton, Isodectes) the lower jaw has a large symphysial tusk and a long retroarticular process. The new material, however, is primitive in having a small posterior meckelian fossa. Advanced lower jaw characters are an overall dorsoventral compression and a uni... |
