My investigations of prehistory have led me to the region of Lake Turkana, which is mostly in Kenya but extends into Ethiopia. This is currently one of the alkaline/saline lakes with no outlet in the East African rift system, but at various times in the past has been completely dry, and at others sufficiently filled its basin to overflow and be the source of rivers flowing into either the Indian Ocean (earlier) or the Nile river system (later). This region probably has the richest collection of hominin fossils that has yet been found. The advancing and retreating shorelines have created various layers of sediment and conditions good for preserving fossils, and because so many have been found, the region has attracted special attention of anthropologists looking for them. Between Kenya and South Africa, the other region where ancient fossils have been found, there are Zaire, and Zimbabwe. I would like to see more information from those areas. It may be that political conditions have not been highly favorable to research, and I’m not sure that physical conditons were conducive to fossilization.
