The Kosarzyska section of the Niedzica Succession, Pieniny Klippen Belt, Poland yielded the Late Albian planktonic foraminiferal biozones from Rotalipora ticinensis-Planomalina praebuxtorfi to Planomalina buxtorfi — Rotalipora appenninica (sensu Gasinski 1988). The Early Cenomanian microfaunal zones have not been recognized in this section due to tectonic disturbances. The Late Cenomanian Rotalipora cushmani zone has been recognized contacting with the Upper Albian strata. Quantitative distribution of bathymetrically diagnostic planktonic species does not correlate to the standard eustatic curve.
