Abstract
The Upper Miocene Gram Formation is famous for its rich molluscan and vertebrate fossil content, representing a diverse marine fauna in the ancient North Sea. In contrast only one echinoderm species has been reported from this formation. Here, we describe the brittle-star species Ophiura huebnerjenseni sp. nov. on the basis of dissociated ossicles, representing the first record of the class Ophiuroidea from the Gram Formation. Among the bulk sediment samples examined, only those taken in the direct vicinity of a partial fossil whale skeleton yielded ossicles of the new brittle-star species. The evidence at hand suggests that material described in the present paper represents the first case of an ophiuroid associated with a whale fall in the fossil record.
