A systematic account of Tertiary Pteropoda (Gastropoda, Euthecosomata) from Austria

The taxonomy and stratigraphical distribution of euthecosomatous gastropods (Pteropoda) from Tertiary sediments in Austria are discussed. Most of the material studied originates from the so-called Molasse Zone and from the Vienna Basin. Eighteen species are recognised within the genera Limacina, Creseis, Clio, Vaginella and Cuvierina, of which twelve are recorded from Austria for the first time. Stratigraphically, the pteropod species discussed herein range from the Late Eocene (Priabonian) to the Middle Miocene (Early Sarmatian).
