Beaufort Series

Beaufort Series

The Beaufort Series is a geological formation forming part of the Karoo System and is rich in synapsid or mammal-like reptile fossils. The Karoo System comprises, from oldest to youngest, Dwyka, Ecca, Beaufort and Stormberg Series. The name is derived from the district of Beaufort West. The formation reaches a thickness of 6-7 km and extends from the latter half of the Permian to the early Triassic. It is customarily divided into zones named after prevalent fossil types. From oldest to youngest these are: "Tapinocephalus", "Endothiodon", "Cistecephalus", "Lystrosaurus", "Procolophon" and "Cynognathus".

The Beaufort Series covers the entire Karoo, Transkei, Pondoland, eastern Orange Free State and western Natal, while the overlying Stormberg Series covers the entire Lesotho and surrounding areas. [Standard Encyclopaedia of Southern Africa]
