Cremation graves appear in different forms and shapes, from urns to simple pits and from single to plural graves. The challenging nature of highly fragmented cremated human remains renders the identification of multiple individuals within the same cremation grave rather complex. Osteological analyses alone are often insufficient to detect the presence of bone fragments from different individuals as they are small and diagnostic elements are often missing, although, detection of nonadult bone fragments within adult bone assemblages (or the other way around) points to the presence of at least two individuals—one adult and one nonadult—within the same grave. The combination of osteological analyses, radiocarbon dating, and strontium isotope ratios has proven to be particularly powerful. At different Belgian Metal Age sites, this novel multi-disciplinary approach enabled to identify the presence of bone fragments belonging to up to three different individuals within the same cremation grave who were cremated up to several centuries apart. Whether the presence of these two or three individuals in the same grave is intentional (e.g. curation) or not requires more in-depth analyses. This study shows the high level of complexity of cremation burial (intentionally or not) and shows the necessity to carry out all analytical measurements (i.e. radiocarbon dating, infrared, elemental and isotope analyses) on the same bone fragment to ensure the results are related to the same individual.

In 2015, a domed oven from the late fifth millennium cal BC was excavated near Kortrijk, northern Belgium. In terms of its size, tripartite structure, stone flooring and well-preserved domed combustion chamber, the oven is unique in Neolithic Western Europe, although mostly smaller, less well-preserved parallels are known in northern France. Such features are thought to have appeared in Western Europe in the Early to Middle Neolithic periods (post-Linearbandkeramik Culture). Their appearance and possible use for drying cereals may be related to a change from individual (household) to communal processing of cereals, and!or indicate adaptation to a wetter climate by newly settled agro-pastoralist communities. Keywords: Belgium, Kortrijk, Neolithic, Michelsberg Culture, domed oven, Introduction Excavations in 2015 near the city of Kortrijk in north-western Belgium revealed an oven structure of Middle Neolithic (Michelsberg Culture) date. Its large size, tripartite structure and indications of [...]

Chronological and stratigraphic frameworks are of the utmost importance for Upper Paleolithic archaeology, physical anthropology, and ecology. Wide ranging radiocarbon (14C) dates were previously obtained for the Sungir burial complex in the central part of European Russia, which is well-known as the richest funeral Paleolithic assemblage in the world yet recorded. The major problem was the contamination caused by consolidants used during the recovery of human bones in the 1960s. The stratigraphy and spatial structure of the Sungir site were also not well understood previously. New radiocarbon and stable isotope data are generated for the Sungir burials. While some dates were younger due to incomplete removal of contamination, the XAD 14C age on S-1 burial (ca. 29,780 BP) was found to be statistically the same as the previously performed HYP 14C age for this burial (ca. 28,890 BP). Four animal bones found in cultural layer below the burial date to ca. 28,800–30,140 BP, suggesting that both this layer and human burials date to roughly this age range. Narrowing these ages further is difficult considering the larger errors of the 14C dates. This shows that future research attempting to 14C date material excavated many years ago needs to eliminate potential contamination from consolidants through analyses such as FTIR, prior to 14C dating. The chronology and stratigraphy of Sungir do not contradict to correlation of its lithic artifacts with the Streletskian assemblage as the East European variant of the Final Szeletian technocomplex (Early Upper Paleolithic).

Megacarnivore behaviours shape ecological dynamics between their prey and competitors and therefore play a key role in structuring ecosystems. In Late Pleistocene Eurasia, hominins and hyenas were sympatric predators. Since the first discoveries of Crocuta c. spelaea in the 19th century, this 'bone‐crushing' species has been identified at most Palaeolithic sites and has inspired many taphonomic studies. Nonetheless, there is still very little known about its reproductive, social and spatial behaviours. We believe that exploring the complexity of the cave hyena's ethology is a way to better understand spatial relationships and niche sharing/partitioning between hominins and other top predators in Pleistocene ecosystems. This paper focuses on the study of Caverne Marie‐Jeanne Layer 4 (Hastière, Belgium), one of the best‐preserved palaeontological sites in the region. The exceptional number of hyena neonates in this assemblage (minimum number of individuals >300) has led us to describe, for the first time, a Late Pleistocene hyena birth den that was reused over a long period of time around 47.6–43k a bp. By bridging the gap between archaeology and palaeontology, we explore the potential of carnivore socio‐spatial organisation and denning habits as an ecological proxy and discuss how these new unique data could help us further understand hominins' spatial strategy in southern Belgium.

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 (δ13C, δ18O) 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 18O-depleted atmosphere (due to the influence of lignin-derived oxygen rather than cellulose-derived oxygen), resulting in more pronounced decrease in the δ18Ocarb 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 δ18Ocarb 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 latest data on holes in the spinous processes of the vertebrae of woolly mammoths, a rare pathology, are presented. This was identified at 19 sites of northern Eurasia. Such destructive changes are recorded ca. 34–12k 14C a bp, and only two sites dated to >50k and >41k 14C a bp. The main hypotheses about hole formation are: vertebral abnormalities; bone infections; genetic traits; and unfavourable geochemical environment. The pathology occurred in mammoths of all age groups, and could have arisen at the embryonic stage. There are two types: classic holes associated with osteolytic changes; and very rarely tumour‐like lesions. The most likely cause of the lesions is alimentary osteodystrophy caused by chronic mineral starvation. The aetiology of this disease is usually associated with a deficiency or excess of macro‐ and microelements in the geochemical landscape, and through forage and water this leads to a severe metabolic disorder. Analysis of palaeopathological data shows two waves of geochemical stress in animals, ca. 26–18k and ca. 16–12k 14C a bp. Therefore, the woolly mammoth extinction can be viewed as a non‐linear function, with two peaks of high mortality corresponding to the Last Glacial Maximum and the Lateglacial.

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.

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.

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 (14C) 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.
