Inproceedings Reference The biodiversity of the Eocene Messel vertebrates based on the Belgian Collections
The paleontological collections of the Royal Belgian Institute of Natural Sciences include a beautiful collection of 393 vertebrate specimens from the Messel Pit: 58 fish, 18 amphibians, 79 reptiles, 108 birds and 130 mammals. This collection is the largest Messel collection outside Germany and belongs to the „big four” (Smith et al. 2024). It results from a fieldwork partnership with the Seckenberg Research Institute, Frankfurt between 1982 and 1988, so a few years before the Messel pit was listed in 1995 as UNESCO World Heritage site. With a few exceptions, most of the specimens have been collected by the Belgians. However, most of the specimens have been prepared by German preparators. Here we show the Messel biodiversity based on the Brussels collection. The collection is relatively well diversified and contains 24 type and figured specimens. Among them are remarkable specimens such as the holotype of the hyaenodont carnivorous mammal Lesmesodon edingeri, the paratypes of the trogon bird Masillatrogon pumilio and embalonurid bat Tachypteron franzeni, the exquisitely 3-D prepared turtle lovers Allaeochelys crassesculpta and armored crocodylia Diplocynodon deponiae, and the only skeleton of the basal perissodactyl Hallensia matthesi housed in a public collection. The archives related to this collection are currently being digitized and several new studies are now based on micro-CT scan technology allowing to „discover” hidden characters.

Article Reference Bioerosional marks in the shells of two sea turtle taxa from the middle Eocene of Belgium
This study analyses the diverse types of bioerosion marks on the shells of two sea turtle specimens from the Lutetian (middle Eocene) of Belgium. The objective is to understand the physical stressors affecting these organisms in ancient marine environments and to identify the potential factors responsible for these changes. The first specimen, the holotype of Eochelone brabantica, presents multiple erosive anomalies on its costal plates. The second individual, corresponding to Puppigerus camperi, exhibits different types of shell deviations, also of an erosive character. The combination of macroscopic and imaging techniques (i.e., CT scanning and 3D surface scanning) allow us the precise observation and identification of the different alterations. Comparative analyses suggest several external factors as potential causes of the anomalies of the two specimens (i.e., invertebrate feeding traces and trauma). This detailed examination provides specific insights into the types and causes of shell alterations in these Eocene turtles, offering a clearer understanding of their interactions in the marine ecosystem in which they lived.

Inproceedings Reference Disabled individuals in a Belgian medieval Cistercian monastic community: a palaeopathological perspective.
Throughout human history, disabilities and impairments have been an inherent aspect of societies, deeply influenced by cultural contexts and by the diverse forms they manifest. Some of the physical and/or mental impairments leave skeletal traces detectable by palaeopathologists. This study presents notable cases of important disorders, such as disproportionate dwarfism, bilateral calcaneus varus (clubfoot) with evidence of crutch use and cerebral palsy. All these pathological individuals were buried in the Cistercian Abbey of the Dunes in Koksijde (Belgium), which was most active between the 12th and 15th centuries. Their grave locations are diverse, ranging from the cloister to the lay brother cemetery. There was no detected difference in their funerary treatment, except one “adapted” burial caused by a physical deformity resulting from cerebral palsy. Most of the identified pathologies are profoundly disabling, with many being congenital and detectable either at birth or during early childhood. Yet all cases presented in this study reached adulthood, with some even surviving into advanced age (over 60 years), suggesting that they received care and support from a young age. Possible health challenge encountered, as well as the nature of the assistance received will be discussed. The prevalence of disabilities within this monastic community raises questions about the social consequences of visible congenital anomalies. Were these individuals placed in a religious institution due to their disabilities, or did they choose monastic life for other reasons, as it might have offered opportunities to develop talents that did not rely on physical abilities? Interestingly, historical texts provide no specific mention of disabled individuals within the context of this abbey, making it challenging to determine whether they were fully integrated into the monastic community or were laypersons and/or benefactors.

Article Reference L’alimentation des anciens habitants de l’île de Pâques.
Comment vivaient les Rapanui, les anciens habitants de l’île de Pâques, il y a plusieurs siècles ? Et surtout, que mangeaient-ils ? Pour le savoir, les anthropologues se penchent sur une source d’information directe et inestimable : les restes humains et plus précisément les os et les dents. Mais leurs investigations ne s’arrêtent pas là. Ils cherchent aussi à comprendre comment des facteurs comme le sexe, l’âge ou le statut social pouvaient influencer l’accès aux différentes ressources alimentaires

Article Reference Étude des pathologies bucco-dentaires dans trois populations mérovingiennes de Belgique
Notre étude porte sur les pathologies bucco-dentaires de trois sites mérovingiens de Belgique (Ciply, Braives et Torgny) : plus particulièrement les caries, les abcès et les pertes ante-mortem (PAM). Nous analysons l’impact de diverses variables, telles que le site archéologique, le type de dent, le sexe et l’âge au décès sur la fréquence de ces trois pathologies. Avec un total de 4599 dents étudiées pour un effectif de 423 individus, nos résultats montrent que le nombre de dents conservées varie significativement selon le site d’origine, suggérant que celui-ci exerce une influence notable sur l’état de conservation des squelettes. Nos données montrent que la présence de caries et d’abcès dépend aussi du site. Ainsi, 63 % des Mérovingiens souffraient de caries, avec les plus fortes prévalences à Braives, tandis que l’abcès est présent chez 23 % des sujets avec une fréquence plus élevée à Ciply. Par contre, le nombre de PAM, qui touchait 65 % des individus, ne varie pas selon le site. La combinaison de plusieurs pathologies est observée chez 12 % des individus, avec des taux plus élevés à Ciply et Braives. Pour les trois pathologies, les dents les plus atteintes sont les molaires et, en ce qui concerne les caries, on observe un taux légèrement plus haut du côté droit, laissant penser à une préférence de côté pour la mastication. Concernant l’impact du sexe, les hommes montrent une prédominance de PAM et de caries par rapport aux femmes, mais celles-ci ont une fréquence légèrement plus élevée d’abcès. Comme attendu, les pourcentages de PAM et de caries augmentent avec l’âge chez les adultes. Notre étude révèle que les prévalences des pathologies bucco-dentaires sont influencées par tous les facteurs envisagés. Des inégalités de régime alimentaire et d’hygiène bucco-dentaire pourraient expliquer les différences liées au sexe et à la localisation géographique.

Article Reference Le nain et l’estropié de naissance, deux individus « hors normes » inhumés dans le cimetière médiéval de l’abbaye des Dunes de Coxyde.
Depending on the form it can take, disability is perceived differently by societies. Adequate care tailored to the severity of impairments sometimes determines the survival of disabled individuals. Some of these pathologies leave traces on the skeleton which can be detected by palaeopathologists. We present two “non-conforming” medieval individuals who must have stood out among their contemporaries. They were buried in the cistercian abbey of the Dunes at Coxyde (West Flanders), active mainly from the 12th to the 15th century. The first individual, suffering from disproportionate dwarfism with a normal-sized trunk and short limbs, lived for about forty years before being buried north of the abbey church. The second had a congenital bilateral calcaneus varus foot deformity, along with other serious pathologies indicating a persistence of mobility conditioned by the use of crutches. He passed away after 50 years and was buried in the cloister. If they had not been members of a monastic community or benefactors, would these subjects have had the same quality of life? Beyond the absence of difference in their funerary treatment, the care provided to these particular individuals testifies to their inclusion in medieval society and redefines our perception of their position in past communities. Selon les formes qu’il peut prendre, le handicap est perçu de manière variable par les sociétés. Une prise en charge adaptée à la sévérité des atteintes conditionne parfois la survie de sujets infirmes. Certaines de ces pathologies laissent des traces sur le squelette et peuvent ainsi être détectées par les paléopathologistes. Nous présentons deux individus médiévaux « hors normes » qui ont dû marquer leurs contemporains. Ils ont été inhumés au sein de l’abbaye cistercienne des Dunes de Coxyde (Flandre occidentale), en activité principalement du xiie au xve siècle. Le premier individu, qui souffrait de nanisme disproportionnel avec un tronc de taille normale et des membres courts, a vécu une quarantaine d’années avant d’être enterré au nord de l’église abbatiale. Le second était atteint d’un pied calcaneus varus congénital bilatéral ainsi que d’autres pathologies lourdes qui indiquent une persistance de sa mobilité conditionnée par l’utilisation de béquilles. Il est décédé après 50 ans et fut inhumé dans le cloître. S’ils n’avaient pas été membres d’une communauté monastique ou issus de classes sociales favorisées, ces sujets auraient-ils eu le même parcours de vie ? Au-delà de l’absence de différence de traitement funéraire, la prise en charge de ces individus particuliers témoigne de leur inclusion dans la société médiévale et redéfinit notre vision de leur place dans les communautés du passé.

Article Reference BASE – BAsicranial Sex Estimation: An R package for sexing adult western European individuals from the cranial base morphometry in bioarchaeology and forensic anthropology
Sexing an adult human skeleton from its fragmented remains is a tremendous challenge in both archaeological and forensic contexts. Although reliable sex estimation methods using the os coxae do exist, as well as the possibility of performing a secondary sexual diagnosis within a funerary assemblage, it is essential in the case of fragmented individuals to set up an alternative sex estimation method based on a skeletal element that is both sexually dimorphic and has a high taphonomic survival rate. This study investigated the sexual dimorphism of the cranial base (occipital and temporal bones), through an exclusively metric approach, in 537 identified western European adults. Using logistic regressions, thirteen predictive models were built up, which yielded up to 86.8% accuracy after cross-validation and with a decision threshold of 0.70. BASE is an R package with a graphic user interface that can be used to apply these predictive models to a target adult individual (https://archive.softwareheritage.org/browse/directory/5e3e3753e1f9c360b0ddbebaa2d2b42e5d7686d9). This paper provides measurement definitions, practical details and user recommendations. BASE is a new sex estimation tool which is free of charge, fast and easy to use, and allows anthropologists to collect biological data from larger numbers of individuals, even when their skeletons are highly fragmented and damaged. This new method can certainly contribute to a better understanding of past populations and will be of considerable value to forensic investigations in today’s context of steadily rising numbers of missing persons.
