The Royal Belgian Institute of Natural Sciences(RBINS) holds a collections of well over 7000 Cretaceous fossils that were collected by the RBINS staff in the early 1930ies during the construction of several coal mine shafts in the eastern part of the Belgian Campine Basin. These fossils include ammonites, nautilids, belemnites, bivalves (inoceramids and other), gastropods, crustaceans, brachiopods, echinoderms and other. The majority of the material is from mine shafts 1 and 2 of the Houthalen and Zolder mines, in-between 400 and 600 m below surface. Both mines are located in the eastern part of the Campine Basin. Since their discovery, the majority of this material has never been thoroughly studied and published. Detailed listings of the fauna and an overview in relation to the stratigraphy are absent. In the 1930ies, by the varying amounts of glauconite, chalk, sand, sandstone and the ‘Gyrolithes’ ichnofossils, the sediments between 400 and 600 m depth were interpreted as belonging to the ‘Smectite de Herve’ facies. Therefore, early students referred to fossils from this locality as Campanian in age, while more recent studies and ongoing work document Santonian to Maastrichtian ages with (from bottom to top) the Asdonk and Sonnisheide Members (Vaals Formation), the Zeven Wegen, Beutenaken Marl, Beutenaken Chalk, Vijlen and Lixhe Members (Gulpen Formation). The CRETACAM project aims for fully documenting the lithological, stratigraphical, paleontological and paleo- ecological changes in the Santonian to Maastrichtian sequence of the eastern part of the Campine Basin. In a first step, all locality information of all 7000 specimens was digitalized. In a second and ongoing step, the taxonomy of all specimens will be revised by an international team of paleontologists.
