An overview is presented of belemnitellid faunas of Santonian to Maastrichtian (Late Cretaceous) age in the Mons Basin and in the Brabant-Méhaigne and Maastricht-Aachen-Liège areas (Belgium, southeast Netherlands). As many as twenty-two species of the genera Actinocamax Miller, 1823, Gonioteuthis Bayle, 1878, Belemnitella d'Orbigny, 1840 and Belemnella Nowak, 1913 have been recorded to date. On the basis of these, thirteen zones can be distinguished: three in the Santonian (G. w. westfalica, G. westfalicagranulata and G. granulata), six in the Campanian (G. granulataquadrata, G. quadrata, Blt. mucronata, Blt. woodi, Blt. minor I and Blt. minor II) and four in the Maastrichtian (Bln. obtusa, Bln. ex gr. sumensis/cimbrica, Blt. junior and Bln. kazimiroviensis). Correlative schemes between these zones and those proposed for Norfolk (southeast England) and for the combined Lägerdorf-Kronsmoor-Hemmoor section (northern Germany) are presented. The belemnitellid assemblage of the study area closely resembles that of Norfolk, but differs from the late Campanian faunas of northwest Germany.
