Stratigraphy comments: Kitching (1977, "Distribution of the Karroo Vertebrate Fauna") assigns this locality to the lower and middle Tapinocephalus Zone. Kammerer et al. (2015) and Angielczyk et al. (2016) list this locality as Tapinocephalus Zone, and the latter note that "Day (2013) suggested that strata on this farm likely fall in the stratigraphic interval between 2350 and 2450 m above the base of the Abrahamskraal Formation in this part of the Karoo Basin." Radioisotopic data constrains the likely age of the Tapinocephalus Zone to Capitanian (Rubidge et al. 2013).
