Sulphur isotopic analysis (δ 34 S) is proving increasingly useful in archaeological case studies due to an ever-improving understanding of sulphur isotope variability within ecosystems, recent innovations in mass spectrometry, and its potential to infer aspects of both diet and movement histories in the past. Sulphur isotopic variation across landscapes is highly correlated with lithology but also strongly influenced by the coastline and the sea spray effect allowing researchers to identify mobility through variations in geology and changes in distance from the coastline. When combined with strontium isotope analysis (87 Sr/ 86 Sr), sulphur isotopes have the potential to allow exploration of individual movement histories and to infer species-specific spatial behaviours. This project aims to explore the use of sulphur isotope analyses in the reconstruction of Late Pleistocene herbivore spatial ecology. Focusing on a region of southwest France, this is being approached in three phases: 1) the development and refining of a sulphur isoscape for the Dordogne; 2) the application of sulphur isotope analyses to faunal remains (bone and incremental dentine) from Middle and Upper Palaeolithic study sites in the Dordogne and 3) the integration of sulphur isotope data with strontium isotope data from the same animals.
