Dinocephalia

Dinocephalians (terrible heads) are a clade of large-bodied early therapsids that flourished in the Early and Middle Permian between 279.5 and 260 million years ago (Ma),[1][2] but became extinct during the Capitanian mass extinction event. Dinocephalians included herbivorous, carnivorous, and omnivorous forms.[3] Many species had thickened skulls with many knobs and bony projections. Dinocephalians were the first non-mammalian therapsids to be scientifically described[4] and their fossils are known from Russia, China, Brazil, South Africa, Zimbabwe, and Tanzania.[5][6]read more
