• coordinate estimated from map

• outcrop-level geographic resolution

When: Abrahamskraal Formation (Beaufort Group), Wordian (266.9 - 264.3 Ma)

• Although it is currently mapped within the uppermost Waterford Formation, Ecca Group, it probably lies at the Ecca-Beaufort group contact (M. Day and B. S. Rubidge, ESI, University of the Witwatersrand; pers. comm.). The transition between these two formations represents a change from fully subaqueous deposits of proximal marine or lacustrine delta front settings of the Waterford Formation, to subaerial delta plain/fluvially deposited rocks of the overlying Abrahamskraal Formation. It is, therefore, more likely that the strata lie within the lowermost Abrahamskraal Formation given the subaerial, autochthonous nature of the fossiliferous deposits. Considering the regional geological context, including uranium-lead (U-Pb) dates obtained from volcanic ashes in the nearby Ouberg Pass (Lanci et al. 2013; Day et al. 2022), the fossils are probably Middle Permian (Wordian) in age, dating to approximately 268 Mya.
