Willodene Farm, Locality 14 (Permian of South Africa)

Also known as Beato 238

Where: Western Cape, South Africa (32.2° S, 21.6° E: paleocoordinates 60.4° S, 31.3° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Tropidostoma Assemblage other zone, Hoedemaker Member (Teekloof Formation), Wuchiapingian (259.9 - 254.2 Ma)

• "[...] middle of the Tropidostoma AZ [...] middle of the locally named Hoedemaker Member of the Teekloof Formation (Smith and Keyser, 1995), which we estimate to be late Middle Permian in age" (Sidor & Smith, 2007)

•In Botha et al. (2007) the Hoedemaker Member is said to be entirely Wuchiapingian in age. According to Catuneanu et al. (2005, J. Afr. Earth Sci., 43) the Hoedemaker is Late Capitanian to Early/Middle Wuchiapingian. Recent radioisotopic dates constrain the Tropidostoma AZ to Wuchiapingian.

• group of beds-level stratigraphic resolution

Environment/lithology: crevasse splay; gray, green siltstone and mudstone

• "These sediments occur in 5–10 m thick coarsening-upward sequences interpreted as prograding crevasse splay sequences. They were laid down by repeated overbank flood events emanating from the channel banks and ponding in the lowland flood basins." (Sidor & Smith, 2007)
• "Most of the vertebrate fossils are found in the thick greenishgrey massively bedded siltstone with minor mudstone intercalations that occur between the main channel sandstones. These sediments occur in 5–10 m thick coarsening-upward sequences interpreted as prograding crevasse splay sequences." (Sidor & Smith, 2007)

Size class: macrofossils
