Also known as Waikraal River, Waaikraal River
Where: Western Cape, South Africa (32.5° S, 21.8° E: paleocoordinates 59.4° S, 34.7° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Tapinocephalus Assemblage zone, Abrahamskraal Formation (Beaufort Group), Capitanian (265.1 - 259.9 Ma)
• " [...] Middle Permian Tapinocephalus Zone of the Beaufort Series of South Africa." (Cox, 1969). 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 biostratigraphic and geographic position suggests that the site is in the Abrahamskraal Formation, which is of Capitanian age (see Catuneanu et al., 2005, J. Afr. Earth Sci. 43 figs. 24, 25).
• member-level stratigraphic resolution
Environment/lithology: dry floodplain; hematitic, gray, green, silty mudstone
Size class: macrofossils
Collected by H. G. Seeley, J. S. Marais, S. Marais, T. Bain; N. Hotton III, J. Kitching in 1889; 1961; reposited in the BMNH, BPI, USNM
Collection methods: mechanical, acetic
• " [...] prepared with acetic acid until any identifiable and well-preserved skeletal elements were free of matrix. The shapes of any superficial impressions of bones were conserved by filling them with a hard-setting plastic before starting to prepare the specimen." (Cox, 1969).
