Turkana Basin : ウィキペディア英語版 | Turkana Basin
The Turkana Basin in northern Kenya and southern Ethiopia (immediately adjacent to their convergence with the South Sudan and Uganda) is a site of geological subsidence containing one of the most continuous and temporally well controlled fossil records of the Plio-Pleistocene〔Feibel, C., 2011, "A Geological History of the Turkana Basin." ''Evolutionary Anthropology''.〕 with some fossils as old as the Cretaceous.〔Tiercelin, J.-J., Potdevin, J.-L., Morley, C. K., Talbot, M. R., Bellon, H., Rio, A., Le Gall, B., Vétel, W., 2004, "Hydrocarbon potential of the Meso-Cenozoic Turkana Depression, northern Kenya. I. Reservoirs: depositional environments, diagenetic characteristics, and source rock-reservoir relationships." ''Marine and Petroleum Geology'', vol.21 pp.41–62.〕 Among the Basin's critical fossiliferous sites are Lothagam, Allia Bay, and Koobi Fora. Much of the Turkana Basin today can be described as arid scrubland or even desert, but the center of the Basin holds Lake Turkana (at 3.3 degrees north latitude and 36.05 degrees east longitude), a major East African Rift and alkaline lake that supports a wide array of wildlife and a community of Turkana, Daasanach, Nyangatom and Pokot peoples. ==Geography==
Lake Turkana sits at the center of the Turkana Basin and is flanked the Chalbi Desert to the east, the Lotakipi Plains to the north, Karasuk to the west and Samburu to the south.〔"Atlas of Kenya," Ed. D. E. Warren, The Survey of Kenya, Nairobi 1962.〕 Included within these regions are desert scrub, desert grass and shrubland, and scattered Acacia or open grasslands.〔 Important towns within the Turkana Basin include Lokitaung, Kakuma, Lodwar, Lorogumu, Ileret and Kargi. The Turkana people inhabit the west of the Basin, the Samburu and Pokot people inhabit the south, and the Nyangatom, Daasanach and Borana Oromo peoples inhabit the north and east.〔
