| Stratigraphy comments: "Kitching (1977) listed the type of C. helmoedi in his entry for Kranskraal, and stated that the stratigraphic section on the farm is highly attenuated with the rocks exposed referable to his Cistecephalus and/or Daptocephalus zones. In current terms, this would correspond to the Normandien Formation, and would represent the lower Daptocephalus Assemblage Zone (AZ) of Viglietti et al. (2016), which is Lopingian in age." (Angielczyk & Kammerer 2017)
