...Jan Hofker Abstract "The Oligocene form of Cassigerinella chipolensis (Cushman and Ponton) does not differ from C. boudecensis Pokorny, and the Aquitanian form from the Cipero formation in Trinidad is only slightly different. The inner structure reveals a distinct well-developed toothplate in all...

...) and Cassigerinella chipolensis/Pseudohastigerina micra (O1) are identified. Calcareous nannofossil bioevents recorded in the present study show numerous discrepancies with the Standard biostratigraphic zonal schemes to detect the Middle/Upper Eocene boundary (e.g. the highest occurrences (HOs) of Chiasmolithus...
