| Paleocoordinates: | 59.5° South, 34.7° West | ||||
| Basis of coordinate: | based on political unit | ||||
| Geographic resolution: | small collection |
Time
| Period: | Permian | Epoch: | Guadalupian |
| Stage: | Capitanian | 10 m.y. bin: | Permian 4 |
| Key time interval: | Capitanian | Zone: | Tapinocephalus Assemblage |
| Age range of interval: | 264.28000 - 259.51000 m.y. ago |
Stratigraphy
| Geological group: | Beaufort | Formation: | Abrahamskraal | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: 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). | |||||
Lithology and environment
| Primary lithology: | sandstone | ||
| Secondary lithology: | claystone | ||
| Lithology description: "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). | |||
| Environment: | "floodplain" | Tectonic setting: | foreland basin |
| Geology comments: " [...] deposited mainly by overbank flooding of large meandering rivers of variable sinuosity, draining an extensive alluvial plain [...]" (Catuneanu et al., 2005). | |||
Taphonomy

| Size of fossils: | macrofossils |
