Summary[edit]
DescriptionStone tools from West Africa flaked and polished dolerite celts and "laterite crayons" (lower right) from Kamabai Rock Shelter, Sierra Leone (2061860253).jpg | Photo taken at the Institute of African Studies, Fourah Bay College, Freetown, Sierra Leone in 1968. The celts were probably hafted as axes or adzes and used to shape artefacts (mortars for pounding rice, for example) from wood or other soft materials. The "crayons" were probably used for red colouring. These artefacts date to about 2,000 years ago. |
