Biology:Aloposaurus

From HandWiki

Aloposaurus is an extinct genus of gorgonopsian therapsids from the Late Permian of South Africa. It was first named by Robert Broom in 1910,[1] and contains the type species A. gracilis (holotype AMNH 5317), and possibly a second species A. tenuis.[2] 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).
