Palaeolithic faunal assemblages provide a wealth of information, notably on paleoenvironment, site formation and past human subsistence strategies. However, obtaining a secure interpretation requires the comprehensive taxonomic identification of faunal remains, traditionally done through visual morphological comparison. Due to high fragmentation, bone morphology is often insufficient to taxonomically identify a large proportion of faunal assemblages. Zooarchaeology by Mass Spectrometry (ZooMS) gives the opportunity to identify biological markers preserved in previously undiagnostic fragmentary or worked remains. This dissertation combines the analyses of bone surface modifications with biomolecular analyses in order to investigate the relationship between faunal composition and bone fragmentation, and to assess hominin subsistence behaviour through large-scale applications of untargeted ZooMS screenings. This study explores the synthesis and analysis of comparable data, for both the morphologically identifiable and unidentifiable portion of the same faunal assemblages, by investigating bone assemblages from European sites spanning the arrival of Homo sapiens within territories occupied by the last Neanderthals such as Fumane Cave (Italy), Bacho Kiro Cave (Bulgaria), La Ferrassie and Les Cottés (France). In addition, the recent development of non-destructive proteomic extraction techniques, notably on fragmented Palaeolithic worked bones, required a controlled sampling experiment to determine how sampling techniques such as the eraser extraction method affect ancient bone surfaces at a microscopic level. Through the combination of methods and the integration of complementary datasets, this dissertation demonstrates the potential of the inclusion of ancient protein analysis within the framework of zooarchaeological analysis at Palaeolithic sites.
