This drawing reveals a variety of stone levels, otherwise stratigraphic columns, on Koobi Fora geologic creation on eastern coastline out-of River Turkana for the Kenya. This region try a good ridge out-of sedimentary material where boffins has discover more 10,100 fossils, each other peoples and other hominins, because 1968. This type of fossils services the new scientific study out of human advancement.
River Turkana have a good geologic records you to definitely best the fresh new preservation off fossils.
