AbstractThe concept of equifinality has become one of the greatest difficulties in the field of taphonomy However, new advances in technology have diminished the margins of error in the interpretation of archaeological sites. The use of multivariate statistics and the most recent advances in microscopic analysis of Bone Surface Modifications (BSMs) have enable a less subjective interpretation of site formation processes. Nevertheless, this broader range of methodological approaches also presents some problems. The capacity of laser scanners in processing inconspicuous and superficial cortical alterations, such as trampling marks, has proven to be problematic. This study presents a new advance towards resolving this problem through the use of the HIROX KH-8700 Digital Microscope, whereby detailed digital three-dimensional (3D) reconstructions are able to pick up such minute BSMs. Through the statistical comparison of the David Laser scanner and the HIROX KH-8700 Digital Microscope, this paper contributes to our understanding of said equipment, followed by a significant advance in the characterisation of superficial BSMs. The combination of advanced microscopy and the application of geometric morphometrics highlights a morphological differentiation between two different types of trampling marks, hereby named scratch and graze trampling marks.
