Leeurivier (Permian of South Africa)

Also known as Leeuw Rivier

Where: Western Cape, South Africa (32.4° S, 22.2° E: paleocoordinates 59.8° S, 34.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tapinocephalus Assemblage other 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. 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).

• group of beds-level stratigraphic resolution

Environment/lithology: "floodplain"; sandstone and 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" (general lithology description of the Abrahamskraal Fm. in Catuneanu et al., 2005, J. Afr. Earth Sci. 43).
