Gorgonops torvus

The genus contains up to 6 species with only one being well established, G. torvus. The others five are G. capensis (=Scylacops capensis, S. bigendens), G. dixeyi (=Chiwetasaurus dixeyi), G. eupachygnathus (= Leptotrachelus eupachygnathus, Scymnosuchus whaitsi), G. kaiseri (=Pachyrhinos kaiseri), G. whaitsi (=Scymnognathus whaitsi) with uncertain to dubious validity due to the poorly preserved state of their fossils.
