The type locality of Pseudotextularia elegans (Rzehak), a planktonic index fossil for the interval upper Campanian to Maastrichtian, contains a rich Paleocene foraminiferal fauna with planktonic species diagnostic of the upper Paleocene Globorotalia pseudomenardii zone. The presence of upper Cretaceous specimens, including Pseudotextularia elegans, in this Paleocene fauna can be attributed to reworking. Furthermore, this is the first definite proof of the presence of upper Paleocene rocks in the Waschberg zone [a tectonic zone situated between the outer Vienna basin and the Flysch zone north of the Danube, Austria].
