Also known as Kruitfontein
Where: Western Cape, South Africa (32.8° S, 22.0° E: paleocoordinates 59.7° S, 35.3° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Tapinocephalus Assemblage zone, Abrahamskraal Formation (Beaufort Group), Capitanian (264.3 - 259.5 Ma)
• Kitching (1977, "Distribution of the Karroo Vertebrate Fauna") assigns this locality to the lower Tapinocephalus Zone. This corresponds to the Tapinocephalus Assemblage Zone of Rubidge et al. (1995, South African Committee for Stratigraphy, Biostratigraphic Series No. 1).
•The Tapinocephalus AZ is Capitanian according to Catuneanu et al. (2005, J. Afr. Earth Sci. 43). Since the locality is west of 24°E it very likely is within the Abrahamskraal Fm. (see Catuneanu et al., 2005 figs. 24, 25).
• bed-level stratigraphic resolution
Environment/lithology: "floodplain"; sandstone and claystone
Size class: macrofossils
Collection methods: SAM = Iziko South African Museum, Cape Town

Taxonomic list
•Kitching (1977, "Distribution of the Karroo Vertebrate Fauna") does not mention any pareiasaurs from his two "Grootfontein" collections of the Tapinocephalus zone, but lists B. baini as coming from "Groot Kruidfontein" (erroneously said to belong to the Beaufort West District, ibid., p. 37).
•Thus, the B. baini specimen is included in the present collection.
