Anomocephalus |
The Anomodontia are one of the three major groups of therapsids. They were mostly toothless herbivores. During the Middle Permian they were very diverse, including groups like the Venyukovioidea, the Dromasauria the Dicynodontia, and early very primitive forms like Anomocephalus and Patranomodon. Of these only the Dicynodonts survived to the Late Permian, and became the most successful and abundant of all Permian herbivores, filling ecological niches ranging from large browsers down to small burrowers. Only two dicynodont families survived the Permian extinction, one of which, the Lystrosauridae, soon gave rise to the Kannemeyeridae. These latter were large, stocky, beaked animals that remained the dominant terrestrial herbivore right up until the Late Triassic, when changing conditions (perhaps increasing aridity) caused them to decline and eventually die out. They were replaced by Sauropodomorph dinosaurs.
