Article Reference Macrocranion germonprae n. sp., insectivore proche de la limite Paléocène-Eocène en Belgique
La nouvelle espèce Macrocranion germonpreae du Membre de Dormaal (Groupe de Landen, Belgique) est décrite sur la base de dents jugales isolées. Cet insectivore érinacéomorphe est comparé aux autres espèces du genre Macrocranion d'Europe et d'AmCrique du Nord. M. germonpreae possède les caractères morphologiques d'un Dormaaliinae primitif.

Article Reference Synthèse des données actuelles sur les vertébrés de la transition Paléocène-Eocène de Dormaal (Belgique)
La présente note fournit un historique des découvertes et travaux concernant les vertébrés fossiles de Dormaal (Brabant, Belgique). Une coupe de la dernière fouille entreprise à Dormaal en 1990 est présentée, ainsi qu'un aperçu stratigraphique du gisement tenant compte du nouveau classement lithostratigraphique du Paléogène en Belgique. La liste faunique des vertébrés est réactualisée et des perspectives paléoécologiques et biostratigraphiques sont offertes par les nouvelles collections.

Article Reference Leptacodon dormaalensis (Mammalia, Lipotyphla), un nyctithère primitif de la transition Paléocène-Eocène de Belgique
Gypsonictops dormaalensis Quinet, 1964, décrit à l'origine à partir d'une unique P4/, est attribué au genre Leptucodon. L'espèce L. clormaalensis est redécrite sur la base de fragments mandibulaires et de dents jugales isolées provenant du Landénien supérieur de Dormaal (Belgique), près de la limite Paléocène-Eocéne. La comparaison du Leptacodon belge avec les autres espèces du genre indique que celui-ci est proche de l'espèce-îype L. tener Matthew & Granger, 1921 et semble posséder avec ce dernier. ainsi que L. rosei Gingerich, 1987, les caractères morphologiques les plus primitifs des nyctithères. La phylogénie du genre Leptucodon est également discutée et le genre Plc~gioctenodon Bown, 1979 est considéré comme synonyme du genre Leptacodon.

Article Reference Diacodexis gigasei n. sp., le plus ancien Artiodactyle (Mammalia) belge, proche de la limite Paléocène-Eocène
Les données acquises au cours de fouilles récentes ainsi que la mise en commun du matériel de plusieurs collections du gisement de Dormaal (localitt de référence du Niveau-Repère MP 7) ont permis de rassembler une douzaine de dents jugales de Diacodrxis. L'étude de ce matériel et sa comparaison avec diverses espèces primitives de Diacodrxis de I'Eocène inftrieur d'Europe, d'Amtrique du Nord et d'Asie ont permis de définir la nouvelle espèce, Diacodexis gigasri. Une position phylogénttique est proposée pour cette nouvelle espèce.

Article Reference Présence du genre Wyonycteris (Mammalia, Lipotyphla) à la limite Paléocène-Eocène en Europe
A new species of insectivore, Wyonycteris richardi, is described on the basis of mandible fragments and isolated cheek teeth of the Early Eocene from Dormaal (Belgium), at the Paleocene-Eocene boundary. Nycticonodon and ?Adapisoriculus from Dormaal, and cf. Adapisoriculus from Fordones (France) are considered synonymous with the genus Wyonycteris from Wyoming (USA). Wyonycteris appears to be neither a typical bat nor a nyctitheriid but probably is related to evolved adapisoriculids.

Article Reference On the use of endosteal layers and medullary bone from domestic fowl in archaeozoological studies
The very high incidence of medullary bone in two archaeozoological assemblages of the Roman period was believed to reflect systematic slaughtering of older hens at the end of the egg laying season. In an attempt to test this hypothesis, histological analyses were carried out. Histological data in the literature on ageing of modern fowl and on the development of medullary bone in hens are insufficient for application to archaeozoological material. Bones of modern fowl of known age were analysed with the aim of validating the use of endosteal layers for ageing. In addition, hens with known egg laying stage were studied in order to try and document differences in medullary bone development that could be related to the time of slaughtering (just before, during, or just after the egg laying season).

Article Reference Reappraisal of the morphology and phylogenetic relationships of the middle Eocene alligatoroidDiplocynodondeponiae (Frey, Laemmert and Riess, 1987) based on a 3D-prepared specimen
We describe a three-dimensionally prepared specimen of Baryphracta deponiae from the middle Eocene of Messel (Darmstadt, Germany). Based on a phylogenetic analysis that included the addition of 20 novel scorings for characters previously unavailable for this taxon and the recoding of four additional characters, we found B. deponiae to be nested within Diplocynodon.We propose the new combination Diplocynodon deponiae. The name Baryphracta is thus a junior synonym of Diplocynodon. The small species D. deponiae (∼1 m in total length) shares several features with other species of Diplocynodon, including the presence of two subequal alveoli in the maxilla and dentary, exclusion of the splenial from the symphysis, and the shape of the iliac blade. However, it also differs in a few characters, including the presence of molariform teeth and the extension of osteoderms along the limbs and tail. Such osteodermal cover, which developed very early in ontogeny, easily distinguishes even small-sized specimens of D. deponiae from the co-occurring Diplocynodon darwini. The crocodylian fauna of Messel shows an astonishing diversity including at least seven taxa, with two belonging to the same genus. The two congeners exhibit differences in dentition and size that likely allowed for niche partitioning that minimized competition, thereby allowing them to be syntopic.
