Abrahamskraal, Prince Albert (Permian of South Africa)

Also known as Farm Abrahamskraal

Where: Western Cape, South Africa (32.9° S, 22.0° E: paleocoordinates 59.8° S, 35.4° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Tapinocephalus Assemblage zone, Abrahamskraal Formation (Beaufort Group), Capitanian (264.3 - 259.5 Ma)

• "Tapinocephalus Assemblage Zone, Late Permian" (Dilkes & Reisz, 1996);

•The Tapinocephalus AZ is Capitanian in age according to Catuneanu et al. (2005, J. Afr. Earth Sci., 43). Lithostratigraphic informations are from Catuneanu et al. (2005) as well.

• member-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)

Size class: macrofossils

Reposited in the TMP

• SAM = Iziko South African Museum, Cape Town
