Howesia is an extinct genus of basal rhynchosaur from early Middle Triassic (early Anisian stage) deposits of Eastern Cape, South Africa. It is known from the holotype SAM 5884, a partial skeleton with palate and partial lower jaws and from two paratypes, SAM 5885 and SAM 5886.[1] It was found in the Burgersdorp Formation of the middle deposits of the Beaufort Group (Karoo Basin) and referred to Subzone B of the Cynognathus Assemblage Zone.[2] It was first named by Robert Broom in 1905 and the type species is Howesia browni, named after Alfred Brown.[3]
