The “Hahn’sche Fossilhorizont” at the base of the upper part of the “Spatkalke” beds in the Klettgau area (southwestern Gemany) yields a condensed ammonite fauna of the Convergens und Macrescens subzones of the Lower Bathonian Zigzag Zone. In the lowermost part of the “Hahn’scher Fossilhorizont” occur (in addition to this condensed fauna from the Lower Bathonian) reworked ammonites, which probably stem from the Parkinsoni Zone. The Parkinsoni Zone is confirmed up to the transition between the “Spatkalke” and the “Hahn’scher Fossilhorizont”. Several ammonite taxa that are new for the Lower Bathonian of the Klettgau area, as well as several taxa that are age-diagnostic of the Middle and Upper Bathonian are presented.
