Article Reference Dietary reconstruction of Spy I using dental microwear texture analysis
Spy I from the Meuse River Basin of Belgium is among the most recent Neandertals. This adult lived at the terminus of Marine Isotope Stage (MIS) 3 in cold steppe environments at the northern edge of the habitable zone for Neandertals where plants were relatively scarce. The dietary proclivities of Spy I are reconstructed using dental microwear texture analysis and compared to 33 Neandertals from western Eurasia, MIS 5 to MIS 3. Spy I has an elevated enamel surface complexity suggesting the consumption of course dietary items such as wild seeds, acorns, nuts, and underground storage organs laden with particles of grit. Unlike the young and old individuals from Hortus with low values for anisotropy, Spy I is closest to the adults from this site suggesting a common pattern of masticatory behavior typified this life cycle stage. Like many other Neandertals, Spy I probably consumed plant foods at appreciable levels, some of which were hard and brittle or poorly processed.

Article Reference The upper Eocene-Oligocene carnivorous mammals from the Quercy Phosphorites (France) housed in Belgian collections
The Quercy Phosphorites Formation in France is world famous for its Eocene to Miocene faunas, especially those from the upper Eocene to lower Oligocene, the richest of all. The latter particularly helped to understand the ‘Grande Coupure’, a dramatic faunal turnover event that occurred in Europe during the Eocene-Oligocene transition. Fossils from the Quercy Phosphorites were excavated from the middle 19th century until the early 20th century in a series of sites and became subsequently dispersed over several research institutions, while often losing the temporal and geographical information in the process. In this contribution, we provide an overview and reassess the taxonomy of these barely known collections housed in three Belgian institutions: the Université de Liège, KU Leuven, and the Royal Belgian Institute of Natural Sciences. We focus our efforts on the carnivorous mammals (Hyaenodonta and Carnivoramorpha) and assess the stratigraphic intervals covered by each collection. These fossils are derived from upper Eocene (Priabonian), lower Oligocene (Rupelian), and upper Oligocene (Chattian) deposits in the Quercy area. The richness of the three collections (e.g., the presence of numerous postcranial elements in the Liège collection), the presence of types and figured specimens in the Leuven collection, and some identified localities in the RBINS collection make these collections of great interest for further studies on systematics and the evolution of mammals around the ‘Grande Coupure’.

Article Reference The holothurian subgenus Mertensiothuria (Aspidochirotida: Holothuriidae) revisited.
Mertensiothuria is one of the 20 subgenera currently recognized under Holothuria. The diagnosis of the subgenus is amended with new information on the ossicles found in the longitudinal muscles. The number of species of Mertensiothuria considered to be valid at present is six. These species are redescribed on the basis of new material, type and non-type museum material and on re-evaluation of literature. Two of them, Holothuria hilla and Holothuria aphanes, are transferred from the subgenus Thymiosycia to Mertensiothuria. Four species formerly referred to Mertensiothuria are removed; provisionally they are not referred to any of the known subgenera of Holothuria. Full annotated descriptions or (where the type material was not available) references to the literature are given for each species. An identification key is given to the species belonging to the subgenus Mertensiothuria.

Article Reference The genus Labidodemas (Holothuriidae:Aspidochirotida) revisited with description of three new species and with re-positioning of Holothuria (Irenothuria) macculochi Deichman, 1958
Prior to the present revision the taxon Labidodemas comprised Labidodemas americanum, L. pertinax, L. rugosum and L. semperianum. An up-to-date re- evaluation of the group proved that at least four additional species need to be assigned to it. Three of these are new to science: one has recently been discovered in the shallow waters of KwaZulu-Natal, Republic of South Africa; one originates from Low Island, Australia, and was erroneously identified as L. semperianum, and one stems from South-West Sulawesi, again erroneously identified as L. semperianum. In addition, Holothuria maccullochi, classified in the monotypic subgenus Irenothuria, and Holothuria proceraspina are assigned to Labidodemas; the former as a valid species and the latter as a synonym of L. semperianum. Annotated taxonomic descriptions, distribution maps and an identification key are given. The new observation that L. americanum possesses Cuvierian tubules suggests that its rank remains at generic level rather than at family level as was recently proposed.

Article Reference Secondary sex estimation using morphological traits from the cranium and mandible: application to two Merovingian populations from Belgium
It is generally accepted that the coxal bone is the most reliable bone for estimating the sex of adult subjects. When the coxal bone is not usable, researchers generally turn to methods based on the skull (cranium and mandible). However, these methods are less reliable, because they are largely based on an estimate of the robusticity, which can be influenced by characteristics independent of the sex of the subject. In the context of primary sex estimation, skull-based methods should therefore be avoided. However, by using morphological traits of the cranium and the mandible as part of a secondary sex estimation, we were able to estimate the sex of a relatively large number of individuals with a minimum reliability of 95%. Our study thus illustrates the value of using morphological characteristics of the skull for a secondary sex estimation conducted with a reliable statistical method.
