Article Reference A land micro-mammal fauna from the Early Eocene marine Egem deposits (NP12, Belgium) and the first occurrence of the peradectid marsupial Armintodelphys outside North America
Dental remains of land mammals are sometimes discovered in shallow marine Paleogene deposits of the North Sea Basin. Such is the case for eleven specimens we describe here from the Early Eocene Egemkapel Clay Member in the middle part of the Tielt Formation, found in Ampe quarry at Egem in Northwestern Belgium. The small fauna consists of 6 taxa, including the neoplagiaulacid multituberculate Ectypodus, the erinaceomorph insectivore Macrocranion, the nyctitheriid Leptacodon, an eochiropteran bat possibly belonging to a palaeochiropterygid, an unidentified perissodactyl possibly belonging to an equoid, and a new species of the peradectid marsupial Armintodelphys. The latter represents the first European occurrence of the genus, which was previously only known from the North American late Early and early Middle Eocene of the Wind River and Green River basins in Wyoming and the Uinta Basin in Utah. Biogeographic and biostratigraphic analyses of peradectid marsupials suggest that Armintodelphys dispersed between North America and Europe around the time of the Early Eocene Climatic Optimum. The Egemkapel Clay Member has been dated as middle NP12, early late Ypresian, whereas the Egem mammal fauna can be correlated to the fauna of Avenay from the Paris Basin, which is the international reference-level MP8+9 of the mammalian biochronological scale for the European Paleogene.

Article Reference Dental and tarsal anatomy of 'Miacis' latouri and a phylogenetic analysis of the earliest carnivoraforms (Mammalia, Carnivoramorpha)
One of the earliest basal carnivoraforms, Miacis latouri, previously known by only two teeth from the earliest Eocene of Dormaal, Belgium, is here described based on about 280 new specimens from Dormaal, allowing illustration of almost the entire deciduous and permanent dentition and thus giving information on the dentition of an early basal carnivoraform species and its variability. Based on the dental features, we refer the species to a new genus, Dormaalocyon. We identify possible sexual dimorphism in D. latouri that is less pronounced than in Uintacyon rudis. We also describe for the first time the tarsal bones (calcaneum and astragalus) of D. latouri; these indicate arboreal capabilities for this species. In order to ascertain the position of Dormaalocyon among basal carnivoraforms, we performed a phylogenetic analysis of the carnivoramorphans. Among basal carnivoraforms, three groups are recovered: the Uintacyon group, Oodectes group, and the Vulpavus group. Dormalocyon is one of the most primitive carnivoraforms and is closely related to North American Vulpavus and Miacis species. We propose that the two latter genera are North American with an ancestry that involves the European Dormaalocyon; this implies a dispersal of carnivoraforms from Europe to North America near the Paleocene-Eocene boundary. Finally, the topology of the phylogenetic tree supports a Paleocene radiation of the carnivoraforms, which is presently unknown.

Article Reference Tarsal diversity in the earliest Eocene mammal fauna of Dormaal, Belgium
Mammal teeth bring important information regarding phylogeny and diet. However, postcranial elements, although poorly studied for small Paleogene mammals, can provide other significant data. The purpose of this study is to associate tarsal bones with dental specimens for a systematic identification. We thus chose the Belgian locality of Dormaal (Tienen Formation, Belgium) that has yielded the earliest Eocene mammals of Europe. This particularly rich fauna, dated between 55.5 and 55.8 Ma, occurred during the Paleocene-Eocene Thermal Maximum, a key period in the mammal evolution. It is composed by archaic mammals (“condylarths”, arctocyonids, plesiadapiforms, “insectivorans”…) and also by earliest modern taxa (primates, rodents, carnivoraforms, artiodactyls …), representing about 14,000 dental specimens. 488 tarsal bones are studied according to three methods: morphology, relative abundance and relative size. 12 morphotypes of astragali and 18 of calcanei are discriminated and most of them are identified at the level of species (e.g. the marsupial Peratherium constans), genus or family (e.g. ischyromyid rodents). New perspectives in phylogeny and paleoecology are proposed for further studies implying tarsal bones.

Article Reference On the occurrence of the osteoglossid genus Scleropages (Teleostei, Osteoglossiformes) in the continental Paleocene of Hainin (Mons Basin, Belgium)
Some bony remains, otoliths and squamules belonging to the osteoglossid genus Scleropages are described from the continental Paleocene of Hainin (Mons Basin, Belgium). The hypotheses to explain the occurrence of such a freshwater fish in Europe at that time are discussed.

Article Reference Through the correspondence: the little story of the “Spy bones”.
In the summer 1886, the Neandertal fossils of Spy were unearthed in the so-called Betche aux Rotches cave. Ever since, they have been through many events and have been the stake of discords, sometimes impassioned, between the various protagonists of their discovery and their conservation. The succession of these events will be redrawn here and the positions of each cleared up in the light of the rereading of two archives collections coming from the discoverers, namely the correspondence collection of Maximin Lohest, which is Mrs Dallemagne-Ophoven’s property, and the correspondence collection of Marcel De Puydt, handed over to the Royal Belgian Institute of Natural Sciences (RBINS), which we shall refer to as “the Vercheval collection”.

Article Reference New mammals from the marine Selandian of Maret, Belgium, and their implications for the age of the Paleocene continental deposits of Walbeck, Germany
The early to middle Selandian fossiliferous Orp Sand Member of the Heers Formation in Belgium has regularly been excavated at its type-locality Maret for its rich and diversified selachian fauna. Among the abundant vertebrate remains, extremely rare mammal specimens have been found. Three isolated teeth have been published previously, all with uncertain affinities. The purpose of this study is to present new specimens from the same deposits, including a small well-preserved dentary of an adapisoriculid attributable to “Afrodon” germanicus, a fragmentary upper molar, referred to Berrulestes sp., and a premolar of a large arctocyonid. Among the previous specimens we identified Arctocyonides cf. weigelti. The adapisoriculid dentary offers new clues that allow transferring “Afrodon” germanicus to the genus Bustylus. The five mammal taxa from Maret indicate an age intermediate between reference-levels MP1-5 of Hainin, Belgium and MP6 of Cernay, France and present the greatest correlation with the rich Walbeck fauna in Germany. The deposits from Walbeck were usually thought to be slightly older than the late Thanetian deposits of Cernay. We infer here that the age of Walbeck is likely to be Selandian. The strong differences observed between Hainin on the one hand, and Walbeck and Cernay on the other hand, document a dispersal event from North America to Europe around the Danian-Selandian boundary.

Inproceedings Reference Comparing 3D digitizing technologies: what are the differences?
We tested five 3D digitization systems and one method of 2D+ recording on one object: a human skull from the Royal Belgian Institute of Natural Sciences collection (RBINS). We chose a skull because it has both simple and complex structures and different materials such as bone and enamel within the same object. The results obtained with the different technologies were compared for 3D shape accuracy, texture quality, digitization and processing time and finally price. Our results show that the structured light scanner provided the best results to record external structures, CT was found to be the best to record internal structures and is also the best for recording reflecting material such as enamel. Photogrammetry is a very good compromise between portability, price and quality. RTI is a method of 2D+ recording and is a complementary technique, using the same equipment than photogrammetry, which can capture small morphological.
