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

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 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.

The Final Neolithic and the Bronze Age (3000–800 BC) are periods of great transformations in the communities inhabiting the area of modern-day Belgium, as testified by archaeological evidence showing ...an increasing complexity in social structure, technological transformations, and large-scale contacts. By combining 599 available radiocarbon dates with 88 new 14C dates from 23 from funerary sites, this paper uses kernel density estimates to model the temporality in the use of inhumation vs. cremation burials, cremation deposits in barrows vs. flat graves, and cremation grave types. Additionally, by including 78 dates from settlements, changes in population dynamics were reconstructed. The results suggest a phase of demographic contraction around ca. 2200–1800 BC highlighted by a lack of dates from both settlements and funerary contexts, followed by an increase in the Middle Bronze Age, with the coexistence of cremation deposits in barrows and, in a lower number, in flat graves. At the end of the 14th–13th century BC, an episode of cultural change with the almost generalized use of flat graves over barrows is observed. Regional differentiations in the funerary practices and the simultaneous use of different grave types characterize the Late Bronze Age.
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 (
87
Sr/
86
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
87

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
87
Sr/
86
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)

Awareness of, and debate about, harassment, assault, bullying and intimidation (HABI) in archaeology has grown in recent years, but the issue remains under-researched. Here, the authors present the ...first Europe-wide survey to evaluate HABI in archaeological environments, from field to laboratory and classroom. The survey covers 18 forms of HABI, collecting more than 1000 responses from archaeologists of 49 nationalities. A total of 82 per cent of respondents report at least one HABI experience. The authors conclude that HABI is endemic in European archaeology, being experienced by all genders and ages, in multiple settings and countries. Documenting these behaviours is a critical first step to eradicating them and to achieving equity and safety in the discipline.
Objectives
The Falys–Prangle‐method assesses age‐related morphological changes to the sternal clavicle end (SCE), enabling the observation of mature adults from the 5th decade onwards in unburnt ...human skeletal remains. The aim of this study is to investigate the applicability of the Falys–Prangle‐method on burnt human remains.
Materials and methods
Fifty‐two SCE of 40 cremated individuals (out of 86) from the William M. Bass collection of the Forensic Anthropology Center (Knoxville, Tennessee) of known age‐at‐death and sex are available for assessment. Surface topography, porosity, and osteophyte formation are evaluated, after which the calculated composite score is associated with the corresponding age range as described by Falys and Prangle. The method is also applied on an archaeological case study from Oudenburg, Belgium, dating to the Roman period.
Results
The assessed age ranges strongly agree with the true age ranges (α = 0.828), suggesting the Falys–Prangle‐method to be applicable on burnt human remains. The case study from Oudenburg yields markedly improved age‐at‐death estimates, significantly enhancing our understanding of the age distribution within this community.
Discussion
Information on age‐at‐death is key in the construction of biological profiles of past individuals. The mature adult is often invisible in the archaeological record since most macroscopic age estimation methods do not distinguish beyond 46+ years old. Our study stresses the usefulness of a large‐scale application of the Falys–Prangle‐method, which will increase the visibility of mature adults, especially in archaeological burnt human skeletal collections, where such information is, at present, extremely difficult to obtain.

Objectives
This study aims to increase the rate of correctly sexed calcined individuals from archaeological and forensic contexts. This is achieved by evaluating sexual dimorphism of commonly used ...and new skeletal elements via uni‐ and multi‐variate metric trait analyses.
Materials and methods
Twenty‐two skeletal traits were evaluated in 86 individuals from the William M. Bass donated cremated collection of known sex and age‐at‐death. Four different predictive models, logistic regression, random forest, neural network, and calculation of population specific cut‐off points, were used to determine the classification accuracy (CA) of each feature and several combinations thereof.
Results
An overall CA of ≥ 80% was obtained for 12 out of 22 features (humerus trochlea max., and lunate length, humerus head vertical diameter, humerus head transverse diameter, radius head max., femur head vertical diameter, patella width, patella thickness, and talus trochlea length) using univariate analysis. Multivariate analysis showed an increase of CA (≥ 95%) for certain combinations and models (e.g., humerus trochlea max. and patella thickness). Our study shows metric sexual dimorphism to be well preserved in calcined human remains, despite the changes that occur during burning.
Conclusions
Our study demonstrated the potential of machine learning approaches, such as neural networks, for multivariate analyses. Using these statistical methods improves the rate of correct sex estimations in calcined human remains and can be applied to highly fragmented unburnt individuals from both archaeological and forensic contexts.

•Elemental (Sr) and isotope (Sr, C & O) analyses were performed.•Dental non-metric traits were assessed.•All individuals appear to be local.•A difference in strontium concentrations is seen.•Two ...intersecting graves are spatially and possibly biologically related.•Biodistance analysis suggests the necropoleis contain different gene pools.
This paper contributes to the current debate regarding the ethno-cultural identity and origins of the post-Archaic (5th to 4th centuries BCE) population of the town of Satricum by introducing bioarchaeologial data including strontium isotope ratios, strontium concentrations, δ13C and δ18O values of tooth enamel, as well as dental morphological traits. Previous studies suggested a change in the original Latin population of ancient Satricum as a result of migrating groups called the Volscians coming from the eastern mountainous hinterland of Latium. The purportedly relatively short occupation of Satricum (ca. 150 years) by the Volscians during the post-Archaic period increases the chance of identifying the first generation of migrants coming from the mountains. Individuals from three presumable Volscian necropoleis in Satricum are analyzed. Forty-three third molars were sampled for isotope and elemental analyses. All individuals appear to be “local” based on their strontium and oxygen isotope ratios. However, three individuals have statistically lower strontium isotope ratios than the rest, two of which originate from two intersecting graves. These two also have the lowest strontium concentrations, potentially suggesting they are spatially and possibly biologically related. At the group level, the strontium concentration data show a clear difference between the necropoleis. An additional difference is in the dental non-metric trait frequencies, with a biodistance analysis suggesting the necropoleis contain different gene pools (MMD score of 0.789). It is hard to determine if these data suggest (1) a population that experienced fast and marked gene flow between use of the necropoleis, or (2) a population with large, distinct kin groups using different necropoleis. Nonetheless, the data show that the 5th to 4th century BCE was a period of change in Satricum and this work paves the way for future research as we strive to understand the origins and identities of these peoples.
