Article Reference Étude des vestiges anthropologiques, fauniques et archéologiques découverts dans la Grotte des Enfants à Freyr, Belgique (Néolithique récent)
En 1964, un groupe de spéléologues amateurs de Villers-la-Ville, appelé "Vampire", fouille une cavité dans les Rochers de Freyr situés dans la Province de Namur (Belgique). Les vestiges exhumés sont actuellement conservés au Musée régional d’Histoire naturelle de Mons. Le matériel archéologique est pauvre et composé principalement d’éclats de silex. Il est difficilement datable sans contexte, ni documentation précise. Notre inventaire recense 557 restes humains et 151 restes fauniques. L’étude préliminaire de la faune indique principalement une accumulation de proies par des carnivores et la présence d’animaux fouisseurs. Aucune trace de feu ou de boucherie n’a été notée. L’étude anthropologique montre que, comme dans les nombreuses autres sépultures collectives du Bassin mosan, les squelettes humains sont incomplets et les os fragmentés. Elle révèle qu’au moins six (voire sept) individus ont été placés dans cette grotte. Trois d’entre eux ont été datés au radiocarbone et remontent au Néolithique Récent. Le résultat le plus surprenant est qu’il s’agit uniquement de sujets immatures (ce qui expliquerait le nom donné à la grotte). Le plus jeune serait décédé entre 1 et 3 ans et le plus âgé est un adolescent. C’est à ce dernier qu’appartiendrait le seul crâne conservé. Afin de représenter l’état de conservation de chaque os de cette sépulture collective, nous avons créé des fiches spécifiques aux individus immatures qui pourront être utiles à tous ceux qui étudient des ensembles funéraires rassemblant de nombreux non-adultes. Aucune trace de pathologies graves n’a été relevée mais tous les tibias présentaient des lignes de Harris et 17 % des dents isolées étaient atteintes d’hypoplasie de l’émail dentaire. On dénombre également un cas de spina bifida atlantis. Parmi les particularités anatomiques, signalons une perforation olécranienne de l’humérus, une incisive en forme de pelle et une fosse d’Allen sur un des fémurs.

Article Reference Les restes humains non-incinérés d’époque gallo-romaine du Musée Gallo-Romain de Tongres. Une étude anthropologique et paléopathologique
En Belgique, les restes humains datés de la période gallo-romaine restent peu étudiés par rapport aux époques plus récentes. Cela s’explique notamment par la pratique de l’incinération qui est majoritaire à cette période ainsi que par le peu de nécropoles découvertes dans nos régions, en particulier celles comportant des sépultures à inhumation. À travers cette étude, nous avons étudié les ossements humains de 56 individus principalement issus de la nécropole principale de l’importante ville de Tongres (province de Limbourg, Flandre, Belgique). L’espace funéraire fut utilisé du Ier au IVe siècle bien que l’inhumation concerne majoritairement le IIIe et le IVe siècle. Le but de notre approche était de proposer une caractérisation de la population (sexe, âge, stature) ainsi qu’une large étude paléopathologique (pathologies dentaires, infections, fractures, marqueurs de stress non-spécifiques, modifications dégénératives des articulations ainsi que de nombreux cas pathologiques individuels). Les nombreuses observations réalisées ont été confrontées entre elles mais aussi avec des données contextuelles connues telles que le type de tombe, la répartition spatiale, la datation et les résultats de sites similaires. Ce qui nous a permis de distinguer des tendances intéressantes au sein de la population ainsi que des différences en fonction du groupe social. La présente étude a permis de mieux connaître la population de Tongres, l’une des cités antiques gallo-romaines les plus importantes de Belgique, ainsi que les nombreuses pathologies et stress auxquels elle était soumise. Mais également de comprendre leur répartition au sein de l’espace et de la vie sociale et proposer de nombreuses perspectives.
