Abstract

Abstract: Recent techniques applied to taphonomy have made advances in our understanding of bone surface modifications. For many years, differences in bone density according to element and variations in animal size have been considered conditioning factors for many taphonomic processes. While several studies highlight how animal size and density affect fracture patterns and bone preservation rates, variations in cut mark morphology are yet to be confronted against these variables. Here, we assess the effect of these variables and their potential effect on cut mark morphology by comparing a considerable amount of cut marks on different anatomical elements of both suids and bovids. Experimentally produced cut mark samples were then digitally reconstructed using a David Laser scanner that allowed the statistical analysis of each cut mark's shape and form. Geometric morphometric analysis using 2D and 3D landmark models were unable to find substantial differences in cut mark morphologies caused by either element type of carcass size.
