Combining microscopic analysis and GIS to analyse experimental perforations on Columbella rustica shells

This paper focuses on Columbella rustica, a marine gastropod species widely attested within the Upper Palaeolithic and Mesolithic Europe ornamental repertoire. We attempt to characterize four different techniques of perforation on Columbella rustica shells through the application of qualitative and quantitative approaches. Our goal is to record diagnostic technological traces associated with each technique and, finally, build a comparative reference collection to be used for archaeological interpretations. Furthermore, we investigate the morphology of the holes created by each of the tested techniques, along with the distribution of technological traces formed around the shell perforation rim, using GIS. Through the combination of qualitative and quantitative approaches we test the potential of a synergetic analysis for reconstructing ancient ornamental biographies and technological traditions.
