Where: Northern Cape, South Africa (31.5° S, 19.8° E: paleocoordinates 58.6° S, 45.5° W)

• coordinate based on nearby landmark

• hand sample-level geographic resolution

When: Whitehill Formation (Ecca Group), Artinskian (290.1 - 279.3 Ma)

• Rossmann (2000) provides no data on the chronostratigraphy of of the Whitehill Formation. Radiometric ages of the Collinson Fm. (overlying the Whitehill Fm.), however, vary between 270 and 275 Ma (Turner, 1999, J. Afr. Earth Sci. 28(1); Fildani et al., 2007 J. Sedim. Res. 77), and radiometric ages of the basal beds of the Prince Albert Fm. (underlying the Whitehill Fm.) vary between 293 and 285 Ma (Bangert et al., 1999, J. Afr. Earth Sci. 29(1)), implying an Artinskian age for the Whitehill Fm. (see time scales of Gradstein et al. (2004) and Ogg et al. (2008)). Radiometric dating within the Whitehill Fm. of southern Namibia (Werner, 2006, PhD thesis, http://www.opus-bayern.de/uni-wuerzburg/volltexte/2007/2175/pdf/00-Complete_thesis-STD.pdf) corroborates an assigment to the Artinskian.
