Abstract/Summary

In the field of paleoproteomics, ZooMS (Zooarcheology by Mass Spectrometry) has been developed to identify morphologically non-diagnostic animal remains to taxon, offering insights into human subsistence practices. Here, we report new ZooMS analyses of 1,050 Early Aurignacian (ca. 37,000–34,000 cal BP) bone fragments from the site of Le Piage (Lot, France). The studied sample is heavily fragmented and was retrieved through water sieving. In our analysis, we compare the taxonomic identifications of bone remains using traditional morphological attributes with remains identified using ZooMS and discuss the implications of the taxonomic patterns that we uncovered. Our results indicate that, despite small effect sizes, the faunal spectrum identified through ZooMS differs from that obtained through morphological analyses. While reindeer remains the dominant species, bovids and other cervids are more abundantly represented in the ZooMS fraction. Two rare taxa, a hare (Lepus sp.) and a previously unidentified carnivore (Pantherinae/Hyaenidae/Mustelidae), were also identified using ZooMS. In addition, we note an increase of Bos/Bison remains in the sample of spongy fragments that is possibly explained by the use of grease-rich bones and bone portions as fuel. Our work adds new data on patterns of reindeer dominance during the Early Aurignacian and illustrates how ZooMS identifications of screen-recovered fragments can enhance our understanding of Paleolithic subsistence strategies and patterns of site occupation.
