Hottentotsrivier Farm (Permian of South Africa)

Also known as Hottentots River, Hottentot's River

Where: Western Cape, South Africa (32.4° S, 22.0° E: paleocoordinates 59.6° S, 34.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tapinocephalus Assemblage other zone, Abrahamskraal Formation (Beaufort Group), Capitanian (265.1 - 259.9 Ma)

• Kitching (1977, "Distribution of the Karroo Vertebrate Fauna") assigns this locality to the lower and middle Tapinocephalus Zone. Kammerer et al. (2015) and Angielczyk et al. (2016) list this locality as Tapinocephalus Zone, and the latter note that "Day (2013) suggested that strata on this farm likely fall in the stratigraphic interval between 2350 and 2450 m above the base of the Abrahamskraal Formation in this part of the Karoo Basin." Radioisotopic data constrains the likely age of the Tapinocephalus Zone to Capitanian (Rubidge et al. 2013).

• group of beds-level stratigraphic resolution

Environment/lithology: "floodplain"; sandstone and red claystone

• " [...] deposited mainly by overbank flooding of large meandering rivers of variable sinuosity, draining an extensive alluvial plain [...]" (Catuneanu et al., 2005)
• "fining-upward succession of sandstones and purple mudstones containing numerous thin chert bands and rich tetrapod faunas" (Catuneanu et al., 2005, J. Afr. Earth Sci. 43)

Size class: macrofossils

Preservation: mold/impression
