Yengema

Town and cave site in eastern Sierra Leone with one of the few stratified sequences of Palaeolithic and Neolithic stone industries in that country. Crudely flaked picks, choppers, and flake-scrapers; hoe-like tools and backed blades have been found. In another phase, pottery and ground stone tools are found for the first time. Thermoluminescence tests dated the third-phase pottery at c 2000 BC.

A cave site in eastern Sierra Leone which provides one of the few stratified sequences of stone industries yet available in that country. Throughout the succession the implements most frequently occurring are crude choppers and flake-scrapers. In a second phase, bifacial hoe-like objects are also present, while in a third phase pottery and ground stone tools are found for the first time. No clear evidence was recovered of the economy of the site’s inhabitants. The sequence is not securely dated, but thermoluminescence tests indicate an age of around 2000 bc for the third-phase pottery.
