Fossiliferous stratigraphic units in Namibia are not as numerous as in neighboring South Africa, but several formations have provided unique fossil assemblages, particularly the Ediacaran fauna of the Vendian to Cambrian Nama Group, fossil fish in the Carboniferous to Permian Ganigobis Formation and Eocene Langental Formation, typical Permian Gondwanan biota in the Huab, Gai-As and Whitehill Formations, Early Triassic therapsids in the Omingonde Formation, Early Jurassic dinosaur trackways in the Etjo Sandstone and Early Miocene mammals and reptiles in the Elisabeth Bay Formation.
