Article Reference Environmental and climatic inferences for Marine Isotope Stage 2 of southern Belgium (Meuse valley, Namur Province) based on rodent assemblages
The environmental and climatic conditions of the Late Pleistocene of Southern Belgium are here determined for the final part of Marine Isotope Stage 3 (MIS 3) and for MIS 2 on the basis of a study of rodent assemblages. This paper provides a synthesis of several sets of environmental and climatic data from Late Pleistocene sites, all of which are located in southern Belgium. One has previously been published (Caverne Marie-Jeanne), and seven are unpublished (Cavernes de Goyet, Trou des Nutons, Trou du Frontal, Trou de Chaleux, Grotte la Chefalize, Trou du Chˆene, and Trou du Sureau). The habitat weighting and quantified ecology methods are applied to rodent material housed in the Royal Belgian Institute of Natural Sciences (RBINS, Brussels), and previous radiocarbon dates are updated, in order to reconstruct past environments. Among all the sites under analysis, the quantified ecology method shows that Trou de Chaleux corresponds to the coldest temperatures and lowest precipitation. Trou de Chaleux, with a chronology between ca. 15,964–14,014 cal yr B.P., could probably be placed in Greenland Stadial 2 (GS2) or Heinrich Event 1 (HE1). It has a rodent assemblage associated with a predominance of open dry and rocky formations, the most abundant species being the collared lemming and the narrow-headed vole. These data are found to coincide with previous studies carried out on the large-mammal, herpetofaunal, and avifaunal associations of the site, as well as on small-mammal associations from other sites in southern Belgium with similar chronology, such as Grotte Walou. Taken together, this indicates that these latest Pleistocene intervals in southern Belgium were characterized by harsh climatic and environmental conditions. In contrast, the other assemblages under study yielded much more heterogeneous results, frequently inconsistent with an attribution to the Pleistocene. This is likely to be a result of their admixture with Holocene material due to recent intrusions.

Inproceedings Reference Première visualisation tridimensionnelle par tomographie d’un squelette de périssodactyle de Messel (Eurohippus messelensis)
Le Lägerstatte de Messel est un site UNESCO mondialement connu pour la conservation exceptionnelle de ses fossiles de la base de l’Eocène moyen (MP11, 48 à 47 Ma). En effet ces spécimens sont très souvent complets et articulés, et préservent même le contenu stomachal, les poils, quelques traces de tissus mous, ainsi que des fœtus. Au moins cinq espèces de périssodactyles sont connues à Messel, appartenant à au moins trois groupes différents (Ceratomorpha, Lophiodontidae et Hippomorpha). Ces fossiles, bien que très complets, sont généralement préservés sur des plaques de résines ne permettant qu’une observation en deux dimensions et sur une seule face. Ce type de préservation ne permet donc pas d’observer chaque ossement en trois dimensions, et complique donc l’étude anatomique. C’est en partie pour cette raison que les périssodactyles de Messel n’ont été que superficiellement décrits et étudiés, malgré le nombre très important de spécimens, et leur préservation exceptionnelle. Ici, un squelette entier d’Eurohippus messelensis (IRNSB-M-1851) a pu être scanné par microtomographie à rayons X pour la première fois, dans le cadre du projet PerissOrigin. Il s’agit de l’un des cinq spécimens de périssodactyles de Messel appartenant aux collections de l’Institut des Sciences naturelles de Bruxelles, acquis lors des fouilles de 1983 à 1988. La tomographie de ce spécimen est particulièrement difficile de par sa grande taille (70x60cm) et par la préservation sur plaque, mais elle a été rendue possible grâce au Double Tomographe à Haute Energie (DTHE) du laboratoire MatéIS à Lyon (Figure 1), avec une résolution de 75 microns. La plupart des ossements, ainsi que le crâne et les dents ont pu être segmentés, révélant pour la première leur morphologie complète en trois dimensions. Cependant, bien que la face exposée soit très bien préservée, la face non-exposée l’est beaucoup moins, rendant la segmentation difficile. Nous présenterons donc ici les résultats de la segmentation de ce spécimen ainsi que quelques particularités anatomiques d’Eurohippus messelensis. Deux autres squelettes seront prochainement tomographiés, dont l’un appartenant à une espèce de périssodactyle énigmatique, Hallensia matthesi, ce qui permettra de mieux comprendre sa place au sein des périssodactyles.

Article Reference Een zeldzame Otodus obliquus Agassiz, 1843 uit een zand-suppletie op het strand van Dishoek (Walcheren, Nederland)
In this contribution, we describe a tooth of Otodus obliquus Agassiz, 1843, found in sand supplementation material on the beach of Dishoek, Walcheren (The Netherlands). Even though this species has a broad distribution in Paleocene and early Eocene successions in Western Europe, in the Netherlands it was thus far only known to occur reworked in younger strata in the subsurface of the northern part of the country, and has never been described from sand supplementation material. The described specimen was found in material dredged up from the Middeldiep, a trough in the Zeeuwse Banken area. The associated mollusk fauna suggests that the material is derived from the mid-Pleistocene to early Holocene Kreftenheye Formation, in which the described early Eocene tooth likely occurred as reworked. Potentially, it was originally derived from the early Eocene Tielt Formation, outcropping to the south of Brugge, Belgium, and transported by local rivers to the Zeeuwse Banken area during the Pleistocene. Alternatively, flint and chalk material present in the sand supplementation material suggests that the described specimen could also be originated across the North Sea, derived from the early Eocene Harwich and London Clay deposits exposed in Kent and Essex (England) and transported eastwards by the paleo-Thames.
