Ericiolacerta is an extinct genus of small therocephalian therapsids from the early Triassic of South Africa and Antarctica.[1][2] Ericiolacerta, meaning "hedgehog lizard" (from the Latin ericius, "hedgehon" and lacerta, "lizard"),[3] was named by D.M.S. Watson in 1931.[1] The species E. parva is known from the holotype specimen which consists of a nearly complete skeleton found in the Lystrosaurus Assemblage Zone within the Katberg Formation of the Beaufort Group in South Africa,[1][3] and from a partial jaw found in the Lower Triassic Fremouw Formation in Antarctica.[2] Ericiolacerta was around 20 centimetres (7.9 in) in length, with long limbs and relatively small teeth.[1] It probably ate insects and other small invertebrates. The therocephalians – therapsids with mammal-like heads – were abundant in Permian times, but only a few made it into the Triassic. Ericiolacerta was one of those. It is possible that they gave rise to the cynodonts, the only therapsid group to survive into post-Triassic times. Cynodonts gave rise to mammals.
