This research concerns ostrich eggshell beads from Iron Age and Late Stone Age sites in Botswana. Studies in South Africa and Namibia have shown a significant size difference between ostrich eggshell beads found on herders' and hunters' sites. Hunters apparently made smaller ostrich eggshell beads than herders. The objective of the study is to find out if a similar pattern exists in Botswana. Ostrich eggshell beads have been found on both Iron Age (farmer-herder) and Stone Age (hunter) sites in Botswana. The aim of the study is to measure a sample of these beads in order to see if significant differences exist in sizes.
