Show moreUnderstanding Palaeolithic hominin subsistence strategies requires the comprehensive taxonomic identifcation of faunal remains. The high fragmentation of Late Pleistocene faunal assemblages often prevents proper taxonomic identifcation based on bone morphology. It has been assumed that the morphologically unidentifable component of the faunal assemblage would refect the taxonomic abundances of the morphologically identifed portion. In this study, we analyse three faunal datasets covering the Middle to Upper Palaeolithic transition (MUPT) at Bacho Kiro Cave (Bulgaria) and Les Cottés and La Ferrassie (France) with the application of collagen type I peptide mass fngerprinting (ZooMS). Our results emphasise that the fragmented component of Palaeolithic bone assemblages can difer signifcantly from the morphologically identifable component. We obtain contrasting identifcation rates between taxa resulting in an overrepresentation of morphologically identifed reindeer (Rangifer tarandus) and an underrepresentation of aurochs/bison (Bos/Bison) and horse/European ass (Equus) at Les Cottés and La Ferrassie. Together with an increase in the relative diversity of the faunal composition, these results have implications for the interpretation of subsistence strategies during a period of possible interaction between Neanderthals and Homo sapiens in Europe. Furthermore, shifts in faunal community composition and in carnivore activity suggest a change in the interaction between humans and carnivores across the MUPT and indicate a possible diference in site use between Neanderthals and Homo sapiens. The combined use of traditional and biomolecular methods allows (zoo)archaeologists to tackle some of the methodological limits commonly faced during the morphological assessment of Palaeolithic bone assemblages.

Show morePalaeolithic 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.

Show moreUmhlatuzana rockshelter has an occupation sequence spanning the last 70,000 years. It is one of the few sites with deposits covering the Middle to Later Stone Age transition (~40,000–30,000 years BP) in southern Africa. Comprehending the site’s depositional history and occupation sequence is thus important for the broader understanding of the development of Homo sapiens’ behavior. The rockshelter was first excavated in the 1980s by Jonathan Kaplan. He suggested that the integrity of the late Middle Stone Age and Later Stone Age sediments was compromised by large-scale sediment movement. In 2018, we initiated a high-resolution geoarchaeological study of the site to clarify the site formation processes. Here, we present the results of the excavation and propose a revised stratigraphic division of the Pleistocene sequence based on field observations, sedimentological (particle size) analyses, and cluster analysis. The taphonomy of the site is assessed through phytolith and geochemical (pH, loss on ignition, stable carbon isotope) analyses. The results indicate a consistent sedimentological environment characterized by in situ weathering. The analysis of the piece-plotted finds demonstrates semihorizontal layering of archaeologically dense zones and more sterile ones. There was no indication of large-scale postdepositional sediment movement. We show that the low-density archaeological horizons in the upper part of the Pleistocene sequence are best explained by the changing patterns of sedimentation rate Show less

Show moreWe explore if taxonomic analysis of archaeological mollusc assemblages can be used to reconstruct Late Pleistocene (MIS 5–3) coastal environments at Klasies River in South Africa. To obtain a balanced reconstruction, we analyse the large molluscs separately from the so-called incidentals, the small mollusc species. Based on modern mollusc habitat preferences and tolerances we identify four different eco-profiles to help characterise sea surface temperatures and the character of the shore: temperature profile; geographical distribution; substrate; wave interaction. We hypothesise that changes in the Klasies River mollusc community/eco-profiles can be linked to global glacial and interglacial events and we define several testable assumptions. We found that in response to global warming and cooling events, the Klasies River mollusc communities change slightly, yet significantly. Other sources of marine environmental data confirm that average sea surface temperatures gradually decreased, but probably remained within the modern southern east coast range of variation. It appears that coastal sea surface temperatures of the warm Agulhas current were not particularly depressed during the occupation sequence. The character of the coastal topography does change more apparently during the occupation sequence of the sites and with it the mollusc assemblages: from an interglacial rocky shore in the Klasies and two Mossel Bay phases to a more glacial sandy environment during the Howiesons Poort and the MSA III. In conclusion, the temperature tolerance levels of many Klasies River mollusc species are too broad to reflect small changes in sea surface temperatures. However, in conjunction with other eco-profiles and environmental proxies, such as substrate requirements and oxygen isotopes, the temperature approximations are useful, particularly when evaluating large scale sea surface temperature fluctuations. For the characterisation of the shore and substrate we found the eco-profile approach very useful. Show less
