Diet and Ecology of Neanderthals: Implications from C and N Isotopes

Abstract

After reviewing the current knowledge on paleoecological tracking using carbon and nitrogen stable isotopes in fossil bones and teeth, the contribution of this new approach to key questions of Neanderthal diet and ecology is examined. In particular, the determination of ungulate habitat (open environment versus closed forest) is discussed. Thanks to the carbon and nitrogen isotopic differences observed in the main ungulates available as prey to Neanderthal of OIS 3, it is possible to evaluate quantitatively the contribution of different prey in the diet of Neanderthals. The results of this approach suggest that megaherbivores, such as mammoth and woolly rhinoceros, were the most important providers of proteins to the Neanderthal from Saint-Césaire and probably also to one Neanderthal specimen from Spy. In addition, the conclusions of zooarcheological and isotopic dietary determinations are not always in agreement, possibly due to taphonomic biases and site specialization.
