Beeldhouersfontein (Permian of South Africa)

Where: Western Cape, South Africa (32.2° S, 23.9° E: paleocoordinates 63.4° S, 27.4° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Dicynodon Assemblage zone, Balfour Formation (Beaufort Group), Changhsingian (254.0 - 252.3 Ma)

• It is said that the fossils come from the "Daptocephalus zone" (Gow, 1972) which is equivalent to the Dicynodon Assemblage Zone. Geographic and stratigraphic data suggest that the locality is in the Balfour Formation of the Beaufort Group (see Catuneanu et al., 2005, J. Afr. Earth Sci., 43, figs. 24, 25). The Dicynodon AZ is Early and Middle Changhsingian according to Catuneanu et al. (2005).

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; green, calcareous mudstone

• "All the specimens are preserved in fine-grained green mudstone which may or may not form a nodule surrounding the specimen." (Gow, 1972)

Size class: macrofossils

Preservation: concretion

Collected by J. Kitching in 1950; reposited in the BPI
