The stratotype of the Maastrichtian Stage named by the Belgian geologist André Dumont in 1849 is situated in the Netherlands at the St Pietersberg.The original description of the "Maastricht Limestone"? is quoted and the successive historical interpretations of the Maastrichtian Stage are outlined. The Maastrichtian Stage in Belgium is then presented in three areas: the Liège-Limburg region, the Mons Basin, and outliers at Orp-Jauche, Orp-le-Petit, as well as Hockai and some other Hautes Fagnes outcrops.
