Hipposaurus ('horse lizard') is an extinct genus of basal therapsids known from the Tapinocephalus Assemblage Zone of the Main Karoo Basin, South Africa . Chronologically this is within the Capitanian stage of the Guadalupian Series (Middle Permian). The genus was first described by S.H. Haughton as H. boonstrai on the basis of a skull and associated skeleton[1] and was later considered a gorgonopsian in the family 'Ictidorhinidae' by Robert Broom.[2] It is now considered a basal biarmosuchian,[3] but its affinities remain uncertain. Some authors note the similarity of its braincase with that of Herpetoskylax.[4] H. boonstrai is currently known from only two specimens in the Iziko South African Museum, Cape Town.
"H. brinki" is based on a single skull that was described by D. Sigogneau in 1970;[5] however, the poor condition of the holotype means most considerations of biarmosuchians ignore it.
