Tamboers Fontein (Permian of South Africa)

Also known as Tamboersfontein, Tamboer's Fontein

Where: Western Cape, South Africa (32.5° S, 21.9° E: paleocoordinates 59.5° S, 34.7° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Tapinocephalus Assemblage 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 Tapinocephalus Zone. This corresponds to the Tapinocephalus Assemblage Zone of Rubidge et al. (1995, South African Committee for Stratigraphy, Biostratigraphic Series No. 1). Additionally, Lee (1997) states that the fossil (BMNH R1970) comes from the Tapinocephalus Zone.

•The Tapinocephalus AZ is Capitanian according to Catuneanu et al. (2005, J. Afr. Earth Sci. 43). Since the locality is west of 24°E it very likely is within the Abrahamskraal Fm. (see Catuneanu et al., 2005 figs. 24, 25).

• bed-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
