The effects of Class I and II sized bovids on macrofracture formation and tool displacement: Results of a trampling experiment in a southern African Stone Age context

Abstract In this paper we follow from previous experiments that assessed the formation of macrofractures on hunting weapons and trampled tools, and present the results of a new trampling experiment. This new experiment examined the relationship between small bovid trampling and the formation of macrofracture types on replicated stone and bone tools. We also recorded the resulting displacement of the tools in order to assess the relationship between tool morphology and displacement. Three tool types with dimensions similar to southern African archaeological tools were used. The results suggest that small frequencies of certain impact macrofractures occur on tools subject to trampling forces. These frequencies are, however, lower than those generally recorded during hunting experiments. Tool morphologies and fracture combinations are also shown to be important variables in macrofracture analyses. These results contribute to a growing body of experimental data dealing with the relationship between postdepositional processes and macrofracture formation on artifacts.
