Abstract
An incomplete skull of a small sphenodontian lepidosaur from the upper part of the Stormberg Group of southern Africa is referable toClevosaurusSwinton, 1939. It is most closely related toC. bairdifrom the McCoy Brook Formation (Lower Jurassic) of Nova Scotia (Canada) andC. mcgillifrom the Dark Red Beds of the Lower Lufeng Formation (Lower Jurassic) of Yunnan (China). The new specimen is important because it represents the first record ofClevosaurusfrom the Southern Hemisphere. Like many other taxa of Early Jurassic continental tetrapods (crocodylomorph archosaurs, dinosaurs, synapsids),Clevosaurushad an apparently Pangaean distribution.Keywords
