Geography
Country:South Africa State/province:Western Cape County:Prince Albert
Coordinates: 33.0° South, 22.0° East (view map)
Paleocoordinates:59.8° South, 35.6° 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 or Pristerognathus Assemblage
Age range of interval:264.28000 - 259.51000 m.y. ago
Stratigraphy
Geological group:Beaufort Formation:Abrahamskraal
Stratigraphic resolution:group of beds
Stratigraphy comments: "This locality is considered to be low in the Beaufort Group (middle of the 'Tapinocephalus zone,' Upper Permian) [...] " (Reisz & Dilkes, 1992). The middle Tapinocephalus Zone corresponds to the transition of the Tapinocephalus and Pristerognathus Assemblage Zones of Rubidge et al. (1995, South African Committee for Stratigraphy, Biostratigraphic Series No. 1).
Both Tapinocephalus and Pristerognathus AZs are 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. (cf. Catuneanu et al., 2005 figs. 24, 25).
Lithology and environment
Primary lithology: not reported
Environment:terrestrial indet. Tectonic setting:foreland basin
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection excludes:some genera
Collection methods:mechanical,survey of museum collection
Reason for describing collection:taxonomic analysis
Museum repositories:TMP
Collection method comments: Specimen was poorly preserved already but was further badly damaged by serial sectioning using a relatively thick saw blade (Reisz & Dilkes, 1992).
TMP = Transvaal Museum, Pretoria
Taxonomic list comments:Reisz & Dilkes (1992) state that the locality "has yielded, in addition to A. megalops, several therapsids, including Dicynodon, Titanosuchus, Tapinocephalus, and three pristerognathid therocephalians."
