Environmental conditions in the Massif Central during the Upper Palaeolithic using stable isotope tracking ( 13 C, 15 N) of bone collagen from large herbivores
ABSTRACT The environmental conditions experienced by hunter‐gatherers during the second part of the Upper Palaeolithic (ca. 28 000–15 000 cal bp ) are poorly known in the mid‐elevation volcanic mountains of the Massif Central in southern France. The stable isotope ratios of carbon and nitrogen ( 13...
