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.
Objectives
This study investigates vitamin D deficiency patterns in individuals from birth to the beginning of adolescence. Microscopic computed tomography (micro‐CT) evaluation of interglobular ...dentine (IGD) in teeth provides information on the age of disease onset and the number of deficient periods per individual, which will increase our understanding of factors influencing vitamin D deficiency prevalence, including sociocultural practices and latitude.
Materials and methods
Beemster and Hattem, two Dutch 17th–19th century communities, yielded relatively high prevalences of rickets (15–24%) and residual rickets (15–24%). From the affected individuals, a subsample of 20 teeth were selected for micro‐CT scanning. Thin sections were made of 17 teeth, consisting of 6 teeth with and 11 teeth without observable IGD on micro‐CT that were included for method comparison.
Results
About 19 out of 29 (65.5%) individuals (one tooth was deemed unobservable) presented with IGD on micro‐CT. Eight of the 11 (72.7%) individuals without IGD on micro‐CT demonstrated histologically visible IGD. In 40.7% (11/27) of the affected individuals (combined micro‐CT and histology results), vitamin D deficiency was recurrent, and in four individuals, some episodes occurred at approximately annual intervals suggesting vitamin D deficiency was seasonal. In three individuals, IGD occurred in the dentine formed around birth, suggesting maternal vitamin D deficiency.
Discussion
Micro‐CT analysis of IGD is found to be a valuable non‐destructive method that can improve our understanding of the influence of sociocultural practices and latitude on disease development within age and sex groups in past communities.

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.

Studies of funerary practices provide information about many aspects of death in past societies. However, only limited archaeological evidence documents the circumstances under which cremations ...occurred and the person(s) who were performing the funerary rituals. Lying at the border between Atlantic and Continental cultural traditions, the Scheldt and Meuse basins of Belgium represent a unique location to investigate variations in ancient pyre technology and body management, as well as the transfer of knowledge related to cremation techniques during the Metal Ages (ca. 2100-52 BCE). The combined use of Fourier Transform Infrared spectroscopy, and carbon and oxygen isotope analysis of different skeletal elements from cremation deposits from four archaeological sites clearly shows differences between the Meuse and Scheldt basins. Different wood availability or selection, and variations in the skills and/or experience of the cremation operator may explain these results. These observed differences are likely linked to ways in which cremation was performed in the two basins, indicating that during the Metal Ages, burning processes were not homogeneous in the Belgian region. Instead, cremation practices appear to align with the different cultural influences also observed in ceramics and bronze artifacts from the same time period. These observed differences in funerary practices between the two basins in Belgium show the immense potential of combining infrared and carbon and oxygen isotope analyses to investigate cremation rituals in any period and region around the world.

ABSTRACT
The adoption of a new funerary ritual with all its social and cognitive meanings is of great importance to understanding social transformations of past societies. The first known occurrence ...of cremation in the territory corresponding to modern Belgium dates back to the Mesolithic period. From the end of the Neolithic onward, the practice of cremation was characterized by periods in which this rite was predominant and periods of contractions, defined by a decrease in the use of this funerary ritual. This paper aims to quantify such phenomenon for the first time by modeling discontinuities in burial practices through kernel density analysis of 1428 radiocarbon (
14
C) dates from 311 archaeological sites located in Belgium from the Mesolithic to the Middle Ages. Despite possible taphonomic and sampling biases, the results highlight the existence of periods with a large uptake of cremation rite followed by periods of contractions; such discontinuities took place in correlation with changes in the socio-economical structure of local communities, as, for example, during the later Middle Bronze Age and at the end of the Roman Period.

•- Subtle but significant changes in social differentiation between Bronze and Iron Age.•- Sr concentration analysis reveals animal protein intake differences in cremated bone.•- Iron Age individuals ...of higher status consumed more meat.•- 14C and spatial analysis show abandonment of oldest cemetery part between 900 and 800 BCE.
Urnfields were the common type of cemetery in the Late Bronze Age (LBA) and Early Iron Age (EIA) in much of Northwest Europe. Rarely are there clear social or chronological differences between burials apart from changing pottery types. The cemetery of Destelbergen stands out because of the relatively high prevalence of monumental ditches surrounding a selection of graves, indicating a certain status difference between the deceased. Strontium concentrations (Sr) combined with radiocarbon (14C) dates and spatial analysis bring to light clear differences between LBA and EIA traditions. The end of the LBA went hand in hand with the abandonment of the oldest part of the cemetery, which new 14C dates demonstrate was strict. Additionally, Sr reveal changing diets in individuals buried centrally within monumental ditches. In the EIA these individuals present significantly lower Sr than the surrounding burials, potentially the result of a diet richer in animal protein at the expense of plant-based food, a distinction not seen in LBA burials. Even though continuity and equality are reflected in the uniform burial tradition seen within urnfields, this paper’s analyses unlock subtle changes in social attitudes between the LBA and EIA and suggest increasing (dietary) social differentiation in the EIA.
