Coordinates: 32.5° South, 22.2° East (view map)
Paleocoordinates:59.8° South, 34.6° West
Basis of coordinate:based on nearby landmark
Geographic resolution:outcrop
Time
Period: Permian Epoch: Guadalupian
Stage: Capitanian 10 m.y. bin: Permian 4
Key time interval: Capitanian Zone:  Tapinocephalus
Age range of interval: 264.28 - 259.51 m.y. ago
Age estimate: minimum 261.241 ± 0.088 Ma (U/Pb)
Stratigraphy
Geological group:Beaufort Formation:Abrahamskraal
Stratigraphic resolution:group of beds
Stratigraphy comments: Kitching (1977, "Distribution of the Karroo Vertebrate Fauna") assigns this locality to the middle Tapinocephalus Zone. Kammerer et al. (2015) and Angielczyk et al. (2016) list this locality as Tapinocephalus Zone. Radioisotopic data constrains the likely age of the Tapinocephalus Zone to Capitanian (Rubidge et al. 2013).
Lithology and environment
Primary lithology: sandstone
Secondary lithology: claystone
Lithology description: "fining-upward succession of sandstones and purple mudstones containing numerous thin chert bands and rich tetrapod faunas" (general lithology description of the Abrahamskraal Fm. in Catuneanu et al., 2005, J. Afr. Earth Sci. 43).
Environment:"floodplain" Tectonic setting:foreland basin
Geology comments: " [...] deposited mainly by overbank flooding of large meandering rivers of variable sinuosity, draining an extensive alluvial plain [...]" (Catuneanu et al., 2005).
