New insight into prehistoric craft specialisation. Tooth-tool use in the Chalcolithic burial site of Camino del Molino, Murcia, SE Spain

Abstract

The study of non-alimentary tooth wear is an excellent tool to identify the development of specific activities and thus, to delve deeper into the social organisation and complexity of past populations. This paper analyses extra-masticatory wear in the dentition of a sample of 102 articulated skeletons from Camino del Molino, a unique collective tomb that housed 1,348 individuals throughout two contiguous phases spanning much of the 3rd millennium BC. After preliminary macroscopic observation of the dental sample, 8 individuals with cultural dental wear were identified and 5 of them were analysed with SEM. In all cases, the maxillary anterior dentition displays evidence that can be defined as occlusal and interproximal grooves consisting of fine, parallel striations, as well as labial notches and chipping of the enamel. The results suggest that 8 individuals, mostly women, used their dentition in craft tasks, such as in the processing of fibres for textile production, hence representing the earliest evidence of craft specialisation in the Iberian Peninsula and potential proof of a possible sex-based division of labour in a Chalcolithic community.
