| Abstract: | The holotype of Paranthodon africanus (Broom) from the Kirkwood Formation (Lower Cretaceous) of the Algoa Basin, Cape Province, South Africa consists of a partial skull, the bones of which are very similar to those of Stegosaurus. Both sides of the maxillary tooth crowns have a bulbous cingulum and a very prominent central vertical ridge above the large apical denticle that is bordered anteriorly and posteriorly by four to seven smaller denticles. Diagnostically stegosaurian material is also known from the Lower Cretaceous of England (Craterosaurus) and China (Wuerhosaurus) and the Upper Cretaceous of India (Dravidosaurus). |
