Abstract
ABSTRACT. An overview of nine disused Paleogene regional stages from Belgium is presented. Some of these regional chronostratigraphic units were already brought into use in the nineteenth century, but are nowadays considered ill defined and of no use in the light of the modern stratigraphic concepts. An overview of their definition and history is given, together with the argumentation for the abandonment of each unit and its present status. The disused chronostratigraphic units belong to the Paleocene, Eocene and Oligocene series.
