This article explores the changes that occurred in harvesting technology during the dispersal of the Neolithic in the Mediterranean basin. It does so through technological and use-wear analysis of ...flaked stone tools from archaeological sites dated between ca. 7000 and 5000 cal BCE, from the Aegean Sea to the westernmost coasts of Portugal. The main goal is to analyse the transformations that occurred in the harvesting toolkit. Our study reveals dynamics of continuity and change in sickles at a Mediterranean scale, resulting from adaptations of the migrant groups to the newly occupied territories and from processes of technological innovation. Adaptations in the production system of the inserts and in their use-pattern occurred in relation to lithic raw material availability and knappers' skills, but also in relation to the scale of production and farming techniques. A major shift took place in the north-western Mediterranean arc with the diffusion of parallel-hafted inserts, probably as a result of heterogeneous phenomena including the diffusion of new groups, technical transfers, establishment of new interaction networks and new systems of lithic production.
The reconstruction of past demographic patterns is a fundamental step towards a better understanding of human-environment relations, especially in terms of quantifiable anthropic impact and ...population susceptibility to environmental changes. The recently developed Summed Calibrated Probability Distributions (SCPD) approach, based on large collections of archaeological radiocarbon dates, provides a new tool to obtain continuous prehistoric population curves suitable for comparison with palaeoenvironmental time series. Despite a wide application in Mesolithic and Neolithic contexts worldwide, the use of the SCPD method remains rare for post-Neolithic societies. Our aim is to address this visible gap and apply the SCPD approach to South European archeological contexts between the Bronze Age and the transition into the Iron Age (1800-800 cal. BC), then evaluating these results against local archeological narratives and palaeoecological data. We first test the SCPD method at a supra regional scale, ranging from the Ebro to the Danube rivers, and subsequently in five selected regions within this area. We then compare the regional population curves to climate data reconstructed from local palynological records. Our results highlight the contrast between a stable supra regional demographic trend and more dynamic regional patterns. We do not observe any convincing long-term correlations between population and climate, but localized episodes of demographic stagnation or decline are present in conjunction with climatic shifts or extremes. Nevertheless, climate change as a triggering factor should be considered with caution, especially in peripheral areas where the archaeological data is faint, or where local evidence points to contemporaneous, ongoing landscape overexploitation.
Cremation is a complex mortuary practice, involving a number of activities of the living towards the dead before, during, and after the destruction of the bodily soft tissues by fire. The limiting ...information concerning these behavioral patterns obtained from the pyre remains and/or cremation deposits prevents the reconstruction of the handling of the corpse during the burning process. This pioneering study tries to determine the initial positioning of the corpse in the pyre and assess whether the deceased was wearing closed leather shoes during cremation through isotopic (δ

O) and infrared (ATR-FTIR) analyses of experimentally burnt pig remains, used as a proxy for humans. The results obtained show that both the position of feet on or within the pyre and the presence of footwears may moderately-to-highly influence the oxygen isotope ratios of bone apatite carbonates and the cyanamide content of calcined bone in certain situations. By forming a protective layer, shoes appear to temporarily delay the burning of the underlying pig tissues and to increase the heat-shielding effect of the soft tissues protecting the bone mineral fraction. In such case, bioapatite bone carbonates exchange oxygen with a relatively more

values during burning of the shoed feet vs. unshoed feet. The shift observed here was as high as 2.5‰. A concomitant isotopic effect of the initial location of the feet in the pyres was also observed, resulting in a top-to-bottom decrease difference in the δ

values of shoed feet of about 1.4‰ between each deposition level tested. Finally, the presence of cyanamide (CN/P ≥ 0.02) seems to be indicative of closed footwear since the latter creates favorable conditions for its incorporation into bone apatite.
The high temperatures reached during cremation lead to the destruction of organic matter preventing the use of traditional isotopic methods for dietary reconstructions. Still, strontium isotope (
Sr/
...Sr) and concentration (Sr) analyses of cremated human remains offer a novel way to assess changing consumption patterns in past populations that practiced cremation, as evidenced by a large amount of new data obtained from Metal Ages and Gallo-Roman human remains from Destelbergen, Belgium. The Gallo-Roman results show significantly higher Sr and a narrower interquartile range in
Sr/
Sr (0.7093-0.7095), close to the value of modern-day seawater (0.7092). This contrasts with the Metal Ages results, which display lower concentrations and a wider range in
Sr/
Sr (0.7094-0.7098). This typical Sr signature is also reflected in other sites and is most likely related to an introduction of marine Sr in the form of salt as a food preservative (e.g. salt-rich preserved meat, fish and fish sauce). Paradoxically, this study highlights caution is needed when using
Sr/
Sr for palaeomobility studies in populations with high salt consumption.
The Bronze Age in prehistoric Europe represents a perfect case study for analyzing phenomena of cultural change and adoption of innovation in small-scale societies. Specifically, we focus on the ...large-scale introduction and development of the cremation rite in the second millennium bc. Traditionally, the origin of the so-called 'Urnfield culture' has been placed in the Carpatho-Danubian area. From this region cremation burials would have expanded across space and over time towards western and southern territories. In this article an innovative approach is adopted in order to quantify this phenomenon. Through the Bayesian analysis of radiocarbon-dated funerary contexts located in Switzerland and in Catalonia and included in the EUBAR database, the ritual change in these two different regions is modeled in a probabilistic way.
This study aims to better understand the development of group identity, mobility, and health in the Early Medieval Meuse Valley. This is achieved by combining existing demographic and ...palaeopathological information from 73 cremation deposits from Echt, the Netherlands, with new strontium isotope ratios (

Sr) and strontium concentrations (Sr) that are performed on pars petrosa, diaphysis, and rib fragments. Although the surrounding Early Medieval cemeteries practiced inhumation, the initial burial community of Echt persisted in expressing the divergent burial ritual of cremation. Thirty-two radiocarbon dates demonstrate the fifth- to sixth-century cremation deposits to be chronologically separated from the seventh-century inhumations that were preserved in situ, suggesting a subsequent burial community replaced cremation with inhumation in the seventh century. Nutritionally inadequate diets may have contributed to the relatively high prevalence of porotic hyperostosis (~ 34%), resulting from decreasing foods supplies caused by deteriorating climatic conditions. The inhabitants are postulated to have mainly consumed foods originating from the land directly surrounding their farmsteads, expressed by the great variability in the

86
Sr of the diaphyses and ribs (0.7096 to 0.7131), matching the geological complexity of the area. The lack of significant differences between the

Sr and Sr of ribs and diaphyses connotes little change in the geological origin of the foods occurred over time, stressing the importance of the yield of local harvests. In contrast, large differences in childhood (i.e. pars petrosa) vs. adult (i.e. ribs and diaphyses)

The CRUMBEL project aims to investigate the mobility of the former population in Belgium from the Neolithic period until the Early Middle Ages. To reach these research goals different topics will be ...studied. In a preliminary phase, the ancient collections of cremated bone will be documented. A selection of these funerary sites will be studied to understand the mobility using different archaeometric approaches as stable isotopes and radiocarbon dating to obtain reliable information on earlier mobility in Belgium.
The funerary Bronze Age culture in the Belgian part of the Meuse valley is poorly understood due to the challenging nature of cremation deposits that dominate the archaeological record. Only a few ...sites were analysed in that region, limiting the possibilities to reconstruct the development of Bronze Age populations in Belgium. Due to its good preservation and detailed excavation reports, the site of Herstal (Belgium) offers a unique opportunity to finally gain new insights into the life and death of those buried in the Meuse Valley during the Late Bronze Age. A total of 21 graves were analysed using a multi-proxy approach, combining grave typology, osteoarchaeology, strontium isotope ratios (87Sr/86Sr), and radiocarbon dating. The 87Sr/86Sr results show that the individuals of Herstal most likely used a variety of local food supplies while having interactions with other populations in and beyond the Meuse Valley, as demonstrated by the bronze artefacts and ceramics displaying clear influences from Germany, Southern Netherlands, and North-West France. The cemetery most likely shows a local burial style with the presence of two (or even three) individuals in several cremation deposits containing a number of privileged individuals who had access to bronze trading networks.
