Resumen
The fauna from the Campanian and Lower Maastrichtian of northern Belgium and the Maastricht region has boreal affinities, while the taxa from the stratigraphical and geographical ranges of some selected ostracod species from the upper-most Cretaceous of western Europe are discussed. A South-north migration can be traced for Amphicytherura bicornella, Dolocythere arenosa, Eucytherura (Renicyterura) simplex, Hemicytherura unisulcata, Kingmaina hagenowi, Limburgina senonensis, Phodeucythere tenuis, Pseudobythocythere formosa, Trachyleberidea acutiloba, and Veenidea reniformis. Two species seem to deviate from the general tendency: Cytherella (Cytherelloidea) binkhorsti and Eucytherura (subgenus indet.) squamifera occur in the Lower Maatrichtian of Rügen and are present in the Upper Maastrichtian deposits near Maastricht. Asciocythere pokornyi is characteristic for the Upper Campanian in northern Belgium and of the Mons and the Paris Basins. A useful index taxon for the Maastrichtian in western Europe is Paijenborchella (Eopaijenborchella) marssoni.
