Pylaecephalidae is a family of dicynodont therapsids that includes Diictodon, Robertia, and Prosictodon from the Permian of South Africa . Pylaecephalids were small burrowing dicynodonts with long tusks. The family was first named in 1934 and was redefined in 2009.[1] Diictodontidae and Robertiidae are considered junior synonyms of Pylaecephalidae;[2] although Pylaecephalus itself is considered a junior synonym of Diictodon,[3] the name Pylaecephalidae predates these names and therefore takes priority.[1]
