The Tapinocephalus Assemblage Zone is a geological stratum and is the thickest faunal zone of the Beaufort Group, in which has been found a rich variety of early therapsids. The name refers to Tapinocephalus, a genus of large herbivorous dinocephalian therapsids that lived during the Middle Permian Period.
