Abstract

Biometrical analysis of a Belemnella faunule of 264 specimens from interval 0 of the Vijlen Member as exposed at Altembroeck (NE Belgium) shows that most specimens belong to Belemnella (Pachybetemnella) sumensis Jeletzky, 1949, the belemnite index of the early part of the late Early Maastrichtian. Belemnella (Betemnella) cf . praearkhangelskii Naidin, 1964 is restricted to a single level (Bm2). In NW Germany this species is confined to a narrow interval characterizing the middle sumensis Zone. lt is concluded that the Bm2 level at Altembroeck is of special importance for long-distance correlation between the Vijlen Member and the Maastrichtian in NW Germany. In the Altembroeck section, belemnite guards are enriched at certain levels. The belemnite accumulations probably developed as a result of stratigraphic condensation.
