Abstract
    In the extended type area of the Maastrichtian Stage (southern Limburg, the Netherlands; provinces of Limburg and Liege, Belgium; Aachen area, Germany), the pachydiscid Pachydiscus (P) neubergicus (von Hauer, 1858) ranks amongst the rarer species of Campanian-Maastrichtian ammonites. To date, just four specimens are known, which show P (P) neubergicus in this area to have been confined to the Vijlen Member (Intervals 0-6, Gulpen Formation). This would correspond to the basal sumensis Zone to the lower cimbrica Zone, or tegulatus/junior Zone, depending on placement of the Lower/Upper Maastrichtian boundary. Material available has been collected in recent years at the CBR-Lixhe (Liege, Belgium) and ENCI-Maastricht bv (Maastricht) quarries as well as from outcrop 62D-26 at Vijlenerbosch (Vijlen, the Netherlands). Records of P (P) neubergicus, the proposed index for the base of the Maastrichtian Stage, from elsewhere in Europe (northern Spain, SW France, Austria, Denmark, Bulgaria), suggest it to have been fairly long-ranging and show local first occurrences to have been diachronous.
