Abstract:
The use of high-resolution silicone moulds for documenting bone surface modifications, such as cut marks, is common. However, it has not been evaluated whether moulding can affect the originals. In this work, the modification level derived from several moulding-demoulding processes on an experimental sample of cut marks has been characterised using geometric Morphometrics. It has been shown that moulds influence the morphology of cut marks, reducing their variability, and making the sample more homogeneous. These modifications do not affect the identification of cut marks, but if not considered, may have an effect on more specialised studies.
