New records of Early Cretaceous iguanodontian dinosaur remains from the Dutch sector of the North Sea

New finds of skeletal elements (tibia, caudal vertebrae) of iguanodontian dinosaurs are described from the Cleaver Bank (Klaverbank), a glacially derived elevation in the south-central North Sea. It is suggested that these bones were exposed by erosion of the Speeton Clay Formation (Early Cretaceous, Berriasian) in the Cleveland Basin of North Yorkshire, England. Subsequently, they were transported during the late Pleistocene (Weichselian) glaciation, when an ever-expanding ice cap, originating from Scotland, ultimately covered an area in the North Sea Basin that now forms the northwestern part of the Dutch sector.
