The Ediacaran–Cambrian succession in the Nama Group, Nama Basin of southern Namibia, occurs in two sub-basins, Zaris (to the north) and Witputs (to the south), separated by a topographic high (Germs, ). The Nama Group comprises the Kuibis, Schwarzrand, and . The Nama Group of southern Namibia is a candidate for the Terminal Proterozoic Global Stratotype Section and Point (GSSP). Desirable characteristics of a GSSP include a well-preserved index-fossil. The late Precambrian genus Rangea Gürich, , a frond-like fossil composed of repeated foliate elements, is one of the first discovered forms belonging to the now widely known soft-bodied assemblages characterizing the Ediacaran Period. Rangea occurs together with the genera Pteridinium Gürich, , and Ernietta Pflug, , in the lower parts of the Nama Group, Namibia (South West Africa).
