The tip cross-sectional areas of poisoned bone arrowheads from southern Africa

Abstract

Current hunter-gatherers from the Kalahari in southern Africa are well-known for their use of poisoned arrowheads, and it is assumed that this tradition spanned most of the Holocene in the region. Recent archaeological work, however, indicates that the techno-behaviour may have originated sometime during the Pleistocene. Tracing the use of poisoned arrowheads through time is not an easy task. Here I explore the use of the tip cross-sectional area (TSCA) metric to analyse relatively large samples of bone points that are ethno-historically associated with Kalahari San poisoned arrow hunting. I add the southern African poisoned bone arrowhead TSCA range to the previous ranges established for North American atlatl dart tips, North American arrowheads and large thrusting spears. Based on the results obtained from 445 artefacts spanning historical, Later and Middle Stone Age phases, I show that poisoned bone arrowheads may have been in use in southern Africa throughout the last 72,000 years, and that a methodical effort to trace stone-tipped poison arrowheads may be warranted.
