Initially aligned with the Atlantic cultural sphere, the area experienced an increasing influence from the Tumulus culture between the 14th and 11th centuries BCE. This interaction led to significant transformations in material culture and funerary practices, notably with cremations becoming the main rite. To understand the underlying factors behind these changes, the study focuses on human mobility and interactions during this period. Strontium isotope (⁸⁷Sr/⁸⁶Sr) analyses were conducted on 100 cremated human bones from eight archaeological sites in the Upper Seine Valley. In parallel, 96 modern plants were analysed to develop a high-density local bioavailable strontium isoscape. The results reveal the presence of two isotopically distinct human groups, each associated with different land-use strategies. While part of the population sourced their food from the southern Yonne river basin, others favoured the Seine-Yonne confluence area, suggesting structured patterns of resource acquisition. In addition, isotopic outliers indicate mobility between these groups, with one case likely reflecting maternal mobility during pregnancy. With a detailed local baseline and a method adapted to cremated remains, this study provides a refined understanding of population dynamics at the end of the Bronze Age. Working within a well-documented archaeological context and focusing on a restricted area enabled a new understanding of land-use dynamics in the Upper Seine Valley during a key period of cultural transition.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"186 ","pages":"Article 106474"},"PeriodicalIF":2.5,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145957354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Species identification of archaeological leather artifacts provides material evidence for understanding the development of ancient pastoralism and technological levels, while also informing critical decisions in conservation material selection and the reconstruction of historical craftsmanship. Archaeological leathers uncovered worldwide exhibit considerable diversity. However, due to complex burial environments, the epidermal structures of these artifacts are often damaged or entirely lost, making them unidentifiable through traditional morphological methods. Contamination and complex sample matrices impair the biomolecular specificity of existing techniques, limiting taxonomic resolution. DNA analysis has thus provided a novel pathway for species identification of leather artifacts. DNA barcoding represents a prevalent methodology within this domain. Unlike previous DNA barcoding studies that required preliminary identification of relic sources to design specific primers—often leading to sample waste—this study introduces a novel technique that uses only one pair of universal primers to identify unknown species in a single experiment. Moreover, it enables the identification of mixed samples via second-generation sequencing. Specifically, we designed a pair of universal primers based on DNA mini-barcoding and meta-barcoding concepts, allowing accurate species-level identification of 11 historical leather specimens from different periods and preservation conditions. Notably, this method requires only minimal sample input, as little as 1 mg per artifact. This study attempts to identify historical leathers from five different species using a single pair of primers in one experiment. The proposed \"DNA mini-barcode and DNA meta-barcode technologies\" enable highly efficient analysis, reducing sample consumption compared to traditional DNA techniques that rely on screening multiple primers for unknown samples. Furthermore, it enhances taxonomic resolution from the genus to the species level. This approach holds great promise for the species identification of historical leather artifacts.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"186 ","pages":"Article 106450"},"PeriodicalIF":2.5,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145753767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Determining whether the remains of very large mammals (&gt;800 kg) were shaped by human activity or carnivore modification requires robust neotaphonomic frameworks. Systematic patterns of carcass consumption by carnivores have been established, particularly for long bones. Yet research on megafauna, and especially on their cranial remains, are scarce despite their recurrent presence in archaeological contexts. This study investigates bone surface modification patterns on rhinoceros (<em>Ceratotherium simum</em>) and elephant (<em>Loxodonta africana</em>) cranial elements consumed by free-ranging spotted hyenas (<em>Crocuta crocuta</em>) in the Timbavati Private Nature Reserve, South Africa. The sample includes 20 cranial specimens (MNE = 20; 12 rhinoceros, 8 elephant) from individuals of different age groups that died naturally and were subsequently scavenged. Analyses using 40x hand lenses and Dino-Lite digital microscope to document bone surface modifications. Distinct patterns emerged: in rhinoceroses, near-complete destruction of mandibular condyles, coronoid processes, nuchal crest, and maxilla; in elephants, pronounced furrowing on mandibular condyles and the symphyseal region. Integrating these observations with published taphonomic analyses of Eurasian assemblages, a five-stage sequence of cranial exploitation is proposed, paralleling models established for long bone consumption. These results highlight prey species-specific differences in modification intensity linked to bone density, tissue distribution, and feeding strategies. More broadly, they provide comparative criteria for distinguishing hyena from hominin-induced modifications, and the paleoecological significance of megafauna in Pleistocene ecosystems.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"186 ","pages":"Article 106458"},"PeriodicalIF":2.5,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145785801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phylogeny and specific limb bone have little effect on this relationship, indicating that cortical thickness can be used to predict size on diaphysis specimens that cannot be identified to skeletal element or taxonomic level below class. Two predictive equations are developed: a linear regression model for estimating body mass and an ordinal logistic regression model for assigning size class. The accuracy and expected error of predictions show that the models are effective even for heavily fragmented assemblages. Size class is predicted for long bone diaphyseal fragments in two assemblages from Pinnacle Point 5–6N, South Africa, to demonstrate the method's application.

Applied to the Euganean Hills in northeastern Italy, a geochemically diverse volcanic region with an extensive history of stone material procurement, this method enabled the identification of 89 potential quarry features, of which 84.9 % of surveyed features were validated as quarries or anthropogenic cuts. Analysis of the region's quarry morphologies and distribution produced several distinct quarry groupings suggestive of phases of exploitation and two case study sites ideal for future provenance research on Euganean volcanic breccias, whose use in Roman construction is known but whose sourced quarries have yet to be identified. Clustering analysis of spatial and morphometric variables indicated the heterogeneity of quarries in the region, differentiated modern and premodern sites, and provided statistical support for the grouping of quarries.

Under ambient conditions, anhydrite typically hydrates to gypsum, rendering its retention a notably rare phenomenon in an archaeological setting. This prompted questions regarding both its preservation and origin. Certain plants, such as tamarisk, are known to produce calcium sulfate hemihydrate, which dehydrates to anhydrite when burned. Similarly, geogenic gypsum converts to anhydrite upon heating, as occurs in gypsum plaster production. Based on this, we hypothesized that the archaeological layer formed as a result of thermal processes. In this study, we demonstrate that it is possible to distinguish between pyrogenic anhydrite derived from biological versus geological sources. To do so, we conducted controlled heating experiments on geological and synthetic calcium sulfates, as well as on various tamarisk tissues, including bark, green branches, and woody parts. These experiments enabled us to quantify changes in chemical composition, morphology, and atomic-scale structural disorder caused by heating. The structural disorder was assessed using a novel infrared spectroscopic approach we developed, which tracks changes in anhydrite vibrational bands. Our results indicate that the thick anhydrite layer in Qumran Cave 49 originated from the burning of green tamarisk branches circa 2800 years ago, providing new constraints on hydration processes in hyper-arid conditions. This conclusion is supported by evidence of disordered crystallinity, elevated sodium content, and irregular particle morphology of the crystals. The methodology presented here offers a new avenue for identifying the origin of calcium sulfate materials in archaeological contexts, including gypsum plaster found at sites distant from geological gypsum sources. It can help determine whether local biological sources were exploited or if geological materials were acquired through trade.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"186 ","pages":"Article 106477"},"PeriodicalIF":2.5,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145978014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
