Willodene Farm, Locality 1 (Permian of South Africa)

Also known as Beato 238

Where: Western Cape, South Africa (32.3° S, 21.7° E)

• Paleocoordinates: 50.1° S, 21.4° W (Wright 2013)

• 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)

• 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
