Riebeeckosaurus

Riebeeckosaurus is an extinct genus of tapinocephalian therapsids from the Guadalupian epoch of Tapinocephalus [Assemblage Zone|Tapinocephalus Assemblage Zone], lower Beaufort Beds of the Karoo, in South Africa. Only two skulls are known from the type genus.
It was a herbivorous, medium-sized dinocephalian, with a very long, slender snout and a narrow intertemporal region with a narrow sagittal crest.
In 2013, Saniye Güven and colleagues proposed that the genus Avenantia is synonymous with Riebeeckosaurus, representing an immature individual.
