The arrival of new methodological approaches to study microscopic qualities in cut mark morphology has been a major improvement in our understanding of butchering activities. Micro-morphological differences can be detected in multiple different taphonomic alterations on bone cortical surfaces that can later be used to compare different trace mark types. Through this, we can generate studies that are able to diagnose the specific taphonomic agents and activities that produce said traces that can be found on osteological surfaces. This paper presents experimental data that have been studied using micro-photogrammetry and geometric morphometrics, successfully distinguishing morphological differences in cut marks produced by different lithic tool types as well as different raw materials. The statistical results and methodologies presented here can later be applied to archaeological sites; aiding in our understanding of raw material exploitation, tool production as well as the different butchering activities that are present in faunal assemblages.
