All aspects of decapod crustacean palaeontology, palaeoecology and palaeobiogeography will be outlined and discussed in two days of oral and poster presentations, grouped according to subject matter covered. Added to this is a full day of field work in the type area of the Maastrichtian Stage (Late Cretaceous), during which the crabrich type Maastrichtian strata and the peculiar K/T boundary section of the Geulhemmerberg nearby will be visited (Maastricht area, Southern Limburg, the Netherlands). Type material of all Late Cretaceous decapod crustacean taxa described in recent years will be on display at the Oertijdmuseum de Groene Poort, north of Eindhoven in the southeast of the Netherlands, for the duration of the symposium.
