p.704: Three lithologically similar horizons can be discriminated within the Klingnau Formation. They are all a few centimeters to decimeters thick and consist of bioturbated bioclastic beds often containing ammonites: the Subfurcaten Beds at the top of the lower third of the succession (Niortense/Subfurcatum Zone), and the Lower and Upper "Parkinsonien Bank", found around the base of the upper third of the succession, separated by about one to two meters of marls (Fig. 4). They are early respectively late Parkinsoni Zone in age. The occurrence of these horizons is somewhat patchy, but they serve as excellent correlation horizons where they occur.
