Subsistence change, landscape use, and changing site elevation at the Pleistocene–Holocene transition in the Dordogne of southwestern France

The dramatic topography of the Dordogne Valley region of southwestern France has long been recognized as an influence on prehistoric human settlement and subsistence patterns. Previous research on late Pleistocene settlement patterns in this region implies that, as cold-adapted higher-ranked resources became scarce in the lowlands, site location in the Dordogne and adjacent river valleys should shift towards higher-elevation areas during the period from 18,000 to 6500 years BP. This study employs a GIS-based analysis to evaluate the changing settlement patterns in the Dordogne region at this time. While no significant changes in elevation were found during this period, site elevation variance does appear to increase significantly between the Magdalenian and the Sauveterrian. Explanations for this finding are explored using zooarchaeological data from Moulin du Roc, one of the sites in the data set. Results suggest that the Magdalenian period in the Dordogne may not have been as resource-rich as is often assumed.
