Also known as Nieu-Bethesda
Where: Eastern Cape, South Africa (31.9° S, 24.6° E: paleocoordinates 63.0° S, 27.8° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Dicynodon Assemblage Zone zone, Balfour Formation (Beaufort Group), Wuchiapingian to Wuchiapingian (259.9 - 252.2 Ma)
• It is said that the fossils come from the "Daptocephalus zone" (Gow, 1972) which is equivalent to the Dicynodon Assemblage Zone. Geographic and stratigraphic data suggest that the locality is in the Balfour Formation of the Beaufort Group (see Catuneanu et al., 2005, J. Afr. Earth Sci., 43, figs. 24, 25). The Dicynodon AZ is Early and Middle Changhsingian according to Catuneanu et al. (2005).
•Youngoides minor (junior synonym to Youngina capensis) given as Cistecephalus zone by Broom & Robinson (1948), but amended to "Daptocephalus zone" by Kitching (1977). Same situation with Dicynodon woodwardi (synonym to Basilodon woodwardi), given as Cistecephalus zone by Broom (1921), but as "Daptocephalus zone" by Kitching (1977).
