Foraminiferal and calcareous nannoplankton bioevents and changes at the Late Cretaceous–earliest Paleogene transition in the northern margin of Tethys (Hyżne section, Polish Carpathians)
Foraminifera and calcareous nannoplankton from the Cretaceous–Paleogene (K-Pg) transition in the Hyżne section (Outer Carpathians, south-eastern Poland) show a relatively complete biostratigraphic record. Despite the absence of the Pa Zone in turbiditic deposits of the Polish Carpathians, the plankt...
