Hugoskop, Rouxville District (Triassic of South Africa)

Where: Free State, South Africa (30.4° S, 26.8° E)

• Paleocoordinates: 50.7° S, 6.9° W (Wright 2013)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Cynognathus assemblage, subzone B zone, Burgersdorp Formation (Beaufort Group), Anisian (246.7 - 241.5 Ma)

• "Subzone B of the Cynognathus Assemblage Zone, Beaufort Group, Middle Triassic (Anisian)." (Modesto & Damiani, 2003). This biostratigraphic assignment corresponds to the Burgersdorp Formation (see Catuneanu et al., 2005, J. African Earth Sci. 43).

• group of beds-level stratigraphic resolution

Environment/lithology: dry floodplain; siliciclastic sediments

• The Burgersdorp formation was "deposited on a semi-arid, slowly aggrading floodplain drained by sluggish meandering stream channels, which supplied water and sediment to the pedogenically-influenced overbank environments via crevasse splays (Hancox, 1998). Lakes and ponds developed on the floodplain [...]" (Catuneanu et al., 2005, J. African Earth Sci. 43).
