Sideritic fossiliferous concretions from the Eocene Lillebaelt Clay Formation, collected ex situ on the beach at Trelde Naes (Jutland, Denmark) were found to yield two common pteropod species: Heliconoides lillebaeltensis spec. nov. and Heliconoides mercinensis (Watelet & Lefevre, 1885), the latter known to date from a Late Palaeocene-Ypresian interval. A single further specimen might represent the species Limacina pygmaea (Lamarck, 1805), known only from the Lutetian. A study of the dinoflagellate assemblages in six of the concretions allowed an age assignment of Early Lutetian. New taxon: Heliconoides lillebaeltensis n. sp. 12 pp., 13 figs, gr. 8.
