Riebeeckosaurus

Riebeeckosaurus is an extinct genus of tapinocephalian therapsids from the Guadalupian epoch of Middle Tapinocephalus 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 (2.5 m in length, 500 kg in mass) dinocephalian, with a very long, slender snout and a narrow intertemporal region with a narrow sagittal crest.
