| Zusammenfassung |
| The Eocene rocks of the Waschberg-Ždánice Unit were deposited at the northern limit of mass-occurrences of larger benthic foraminifera (LBF). The found LBF-assemblages are well suitable for biostratigraphic classifications and therefore for the reconstruction of the sedimentary and tectonic development of the area. We found 1) a Ypresian to basal Lutetian (SBZ, Shallow Benthic Zone 10-11) assemblage dominated by Nummulites partschi and Orbitoclypeus schopeni, 2) a Bartonian (SBZ 18) assemblage dominated by Nummulites striatus and Orbitoclypeus varians, and 3) a Priabonian (SBZ 20) assemblage dominated by Asterocyclina priabonensis, Nummulites stellatus, and Discocyclina trabayensis vicenzensis. Orthophragminids from this area were studied on species level for the first time. |
