Aloposaurus is an extinct genus of gorgonopsian therapsid from the Late Permian of South Africa. It was first named by Robert Broom in 1910, and contains the type species A. gracilis, and possibly a second species A. tenuis.[1] This small gorgonopsid had a slender narrow skull only 12 centimetres (4.7 in) long, with a total body length of 60–70 cm (2.0–2.3 ft). Aloposaurus is known from a single weathered skull from a probable immature individual.[2]
