Morphometrical Analysis on Cut Marks Using a 3D Digital Microscope

Microscopic analysis represents a powerful tool for understanding taphonomy. Our work, as in other studies, aims to identify the origin of different kinds of marks on bones. In this paper, we test the application of a HIROX Digital Microscope KH-7700. This microscope captures 3D images of the bone surface, thus bringing into focus the whole section of striations. This enables the direct observation of their shape from several points of view and the relatively rapid procurement of a variety of measurements (e.g. depth, breadth, angles). This technology has been applied to several butchery experiments, in which both stone and metal tools have been used to produce cut marks on skeletal elements. The morphometrical parameters presented in this paper enabled the correct identification of the different origins of experimental striations and were further tested on two archaeological sets of cut marks inflicted by both metal blades and flint flakes or tools. Therefore, the obtained experimental records constitute a useful database for archaeological remains. The morphometrical parameters developed and implemented in this study represent objective criteria for identifying the origin of cut marks which can be processed through statistical analysis. © 2011 John Wiley & Sons, Ltd.
