Inproceedings Reference Vestibular sensitivity and locomotor behavior in early paleocene mammals
The end-Cretaceous extinction triggered the collapse of ecosystems and a drastic turnover of mammalian communities. During the Mesozoic, mammals were ecologically diverse, but less than extant species. Modern ecological richness was established by the Eocene, but questions remain about the ecology of the first wave of mammals radiating after the extinction. Postcranial fossils are often used to determine locomotor behavior; however, the semicircular canals of the inner ear also represent a reliable proxy. These canals detect the angular acceleration of the head during locomotion and transmit neuronal signals to the brain to allow stabilization of the eyes and head. Accordingly, vestibular sensitivity to rapid rotational head movements is higher in species with a larger canal radius of curvature and more orthogonal canals. We used high-resolution computed tomography scanning to obtain inner ear virtual endocasts for 30 specimens. We supplemented these with data from the literature to construct a database of 79 fossils from the Jurassic to the Eocene and 262 extant mammals. We compared data on canal morphology and another lifestyle proxy, the size of the petrosal lobules, which have a role in maintaining eyes’ movements and position. We find that Paleocene mammals exhibited a lower average and more constricted range of Agility Indices (AI), a new measure of canal radius size relative to body size, compared to Mesozoic, Eocene and extant taxa. In the early Paleocene, body mass and canal radius increased, but the former outpaced the latter leading to an AI decline. Similarly, their petrosal lobules were relatively smaller on average compared to other temporal groups, which suggests less ability for fast movements. Additionally, Paleocene mammals had similar AIs to extant scansorial and terrestrial quadrupeds. In contrast, the lack of canal orthogonality change from the Mesozoic to the Paleocene indicates no trend toward lower vestibular sensitivity regardless of changes in body size. This result may reflect functional differences between canal orthogonality and radius size. Our results support previous work on tarsal morphology and locomotor behavior ancestral state reconstruction suggesting that ground dwelling mammals were more common than arboreal taxa during the Paleocene. Ultimately, this pattern may indicate that the collapse of forested environments immediately after extinction led to the preferential survivorship of more terrestrially adapted mammals.

Inproceedings Reference Villers-le-Bouillet - Lohincou, un habitat rural du Haut Moyen Âge : résultats préliminaires des études archéobotaniques et archéozoologiques
Suite au diagnostic archéologique effectué dans le parc industriel de Villers-le-Bouillet en 2001 et à plusieurs campagnes de fouille (2002, 2008, 2009 et 2010), une occupation datée du Haut Moyen Âge a été mise en évidence sur le lieu-dit « A Lohincou ». La fouille a livré les vestiges traditionnellement associés aux occupations rurales de la période considérée tels que des fosses, fossés, fonds de cabanes, structures de combustion, empreintes de poteaux, ainsi que la présence au sein de l’habitat d’un groupe funéraire d’au moins 22 individus. Dans l’état actuel des recherches, l’analyse spatiale des vestiges n’offre que peu de clefs de lecture (plans de batiments, zones d’activités spécifiques etc.) permettant d’appréhender l’organisation interne du site, ainsi que son évolution par phases archéologiques significatives. Récemment, la périodisation de l’occupation du Haut Moyen Âge « A Lohincou » a pu être approchée plus finement grâce à des études céramiques et des datations radiocarbones complémentaires. Des prélèvements sédimentaires destinés aux études archéo-environnementales ont été effectués lors des dernières campagnes de fouille. Alors que peu de données bioarchéologiques sont encore disponibles en Wallonie pour cette période, les récents résultats des recherches archéobotaniques et archéozoologiques à Villers-le-Bouillet permettent d’appréhender l’économie de subsistance, les pratiques agricoles et le milieu environnant (exploité ou non pour l’approvisionnement en bois de feu, par exemple) mais aussi de caractériser plus précisément la fonction des structures (carpologie, palynologie). L’intégration des études archéo-environnementales nous renseigne ainsi sur le quotidien des populations rurales du Haut Moyen Âge.

Inproceedings Reference WALOU CAVE (TROOZ): AN EXCEPTIONAL SEQUENCE FROM THE BELGIAN PALAEOLITHIC
Located some 10 km at the south-east of Liège the Walou cave entrance faces the north-west, 25 m above the Magne, a tributary of the Vesdre river. Excavations were conducted at the site from 1985 to 1990 and then from 1996 to 2004, revealing numerous successive prehistoric occupations. Its extensive stratigraphic sequence is the best documented for a Belgian Upper Pleistocene karst site. Thanks to a multidisciplinary approach the chronostratigraphic and palaeoenvironmental framework of the occupations is well understood. Out of the 45 layers of the sequence 25 yielded archaeological material. There are traces of the Neolithic (Layer A2) and the Mesolithic (Layers A4 and A5) at the top. The cave also revealed several Upper Palaeolithic occupations: Federmesser (Layer B1), Gravettian (Layer B5) and Aurignacian (Layer CI-1). The lower half of the sequence, which encompasses the Last Interglacial and the Weichselian Early Glacial, includes 9 Mousterian occupations; 6 reworked layers also yielded some artefacts from that culture. A Neandertal tooth was found in Layer CI-8, which contains the richest Mousterian occupation of the site. All lithic material was made from flint probably sourced in secondary position near the cave. Only the Gravettian and Aurignacian occupations yielded other man-made materials: antler spearheads and animal and mineral non-utilitarian artefacts from the Aurignacian. Numerous faunal remains were also found; among them: cave bear, cave hyena, horse, fox, bison/aurochs, woolly rhinoceros, deer, mammoth, chamois, hare, small rodents and a few birds. The study of the fish remains revealed that fishing took place at the site, as much during the Middle Palaeolithic as during the Upper Palaeolithic and Neolithic.
