From Upper Campanian turbiditic marls at Beckum in the Münster Basin (NW Germany) the anterior portion of a mosasaurid premaxilla with abutting fragments of the left and right maxilla is described and referred to the genus Clidastes. It shows the process of tooth replacement very well. This taxon is recorded for the first time from Germany. Clidastes co-existed in central Europe with other mosasaurids such as representatives of the genus Leiodon and Mosasauridae indet.
