Pteropod species (Mollusca, Gastropoda, Euthecosomata) from the Late Oligocene of Mogenstrup, Jylland, Denmark

Three pteropod species are reported from a Late Oligocene (Chattian B) sediment (Vejle Fjord Formation, Brejning Clay Member) exposed in a coastal cliff near Mogenstrup, Jylland. Among these species Limacina hospes Rolle, 1861 was found here for the first time in sediments of which the age is known, while the species L. valvatina (Reuss, 1867) could be recognised with certainty for the first time from Chattian sediments. The presence of Clio nielseni sp. nov. allows speculations on its possible evolutionary development towards the Pliocene North Italian species C. guidottii Simonelli, 1896.
