Geography
Country:South Africa State/province:Western Cape County:Beaufort West
Coordinates: 32.2° South, 21.6° East (view map)
Paleocoordinates:60.4° South, 31.2° West
Basis of coordinate:estimated from map
Geographic resolution:small collection
Time
Period: Permian Epoch: Lopingian
Stage: Wuchiapingian 10 m.y. bin: Permian 4
Key time interval: Wuchiapingian Other zone:  Tropidostoma Assemblage
Age range of interval: 259.51 - 254.14 m.y. ago
Stratigraphy
Geological group:Beaufort Formation:Teekloof Member:Hoedemaker
Stratigraphic resolution:group of beds
Stratigraphy comments: "[...] 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.
Lithology and environment
Primary lithology:gray,green siltstone
Secondary lithology: mudstone
Lithology description: "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)
Environment:crevasse splay Tectonic setting:foreland basin
Geology comments: "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)
