Inproceedings Reference Varanidé, Saniwa orsmaelensis, de l'Eocène basal du Nord-Ouest de l'Europe
Saniwa est un genre éteint de lézard varanidé de l’Eocène européen et nord-américain et taxon frère du groupecouronne Varanus. Jusqu’à maintenant, seule une espèce, Saniwa orsmaelensis était rapportée en Europe, dans l’Eocène basal de Dormaal, Belgique. Cette espèce, originellement nommée par Louis Dollo il y a presqu’un siècle, est le plus ancien varanidé d’Europe. Malheureusement, le matériel diagnostique était limité à quelques vertèbres, décrites assez brièvement et non figurées, si l’on excepte une vertèbre dorsale désignée comme lectotype. Nous décrivons et illustrons ici de nouveaux spécimens de Dormaal ainsi que du Quesnoy, Bassin de Paris, France, incluant des restes crâniens (maxillaire, dentaires et pariétal), permettant de confirmer la validité de ce taxon européen. Ces nouveaux spécimens permettent en effet de nouvelles comparaisons avec l’espèce-type Saniwa ensidens, de l’Eocène moyen des formations de Bridger et de Green River, Wyoming, Etats-Unis et permettent d’amender la diagnose de S. orsmaelensis. La présence de S. orsmaelensis est restreinte à l’Eocène inférieur du Nord-Ouest de l’Europe et son origine géographique n’est pas encore certaine car Saniwa apparait simultanément en Amérique du Nord en Europe. La présence relativement brève des lézards varanidés dans le Paléogène Européen pourrait résulter des rapides changements environnementaux aux alentours du Paleocene Eocene Thermal Maximum qui ont permis de nombreux échanges fauniques dans l’hémisphère nord. Cependant, le sens de ces migrations n’est pas encore connu. Par ailleurs, les considérations paléogéographiques liées à la distribution du genre Saniwa suggèrent une origine asiatique bien qu’une origine africaine ne puisse être complètement exclue. Ce résumé est une contribution au projet réseau Belspo Brain BR/121/A3/PalEurAfrica financé par le Bureau de la Politique Scientifique Belge.

Book Reference Annotated Iconography of the fossil Chondrichthyan Fishes in the collection of the Royal Belgian Institute of Natural Sciences, Brussels
This book is an extensive iconography of all types of material of Elasmobranchii (mostly teeth) of which the type specimens were found in the collections of the RBINS, in total there are 119 species. Unfortunately, 11 type series were incomplete and 17 were no longer found in the collection at all. The latter are listed in the book, but of course not depicted. It is often about Holocephali from the Paleozoic, but also about some species from the Cenozoic (e.g. Mustelus vanderhoeft, the type of which was never deposited by the author in the RBINS). All species are listed in systematic order, according to the original name, followed by the collection number. The authors have searched the original literature to the type locality and the type stratum as they were specified at the time. Since many species were defined in the19th and early20th centuries, much of that data was outdated, but they were completely revised and adapted to modern nomenclature, a titanic work. Furthermore, the original publication is given species by species and the modern systematic status is given in the notes. The photographs are of high quality and often with more views per copy so that more details are now visible than was possible in older publications. Usually one page per species is provided. It contains an extensive bibliography and the index (with both the old and modern species names) makes searching easier. Thanks to the excellent iconography, the book can also be used as a determination work, but of course only for the types in the RBINS collection.
