Item A new vertebrate biozone at the base of the Beaufort Group, Karoo sequence (South Africa)(Bernard Price Institute for Palaeontological Research, 1990) Rubidge, Bruce SA new vertebrate biozone at the base of the Beaufort Group has been identified. This biozone is the oldest vertebrate biozone of the Beaufort Group and contains fossils of various therapsid genera which are more primitive than previously known related forms from the Karoo. The name Eodicynodon - Tapinocaninus Assemblage Zone is proposed as these two genera of therapsid are the most plentiful from this biozone and have not been found in the rocks of the overlying Dinocephalia Assemblage (Tapinocephalus) Zone.
