Benthic foraminiferal assemblages from the Brendola section (Priabonian stage stratotype area, northern Italy): Distribution, palaeoenvironment and palaeoecology
As part of a complete micropaleontological reevaluation of the Brendola section, one of the three Late Eocene stratotype sections, we studied the benthic Foraminifera. This is the first precise study of the Eocene-Oligocene boundary in this section. We applied the paleobathymetric zonation for Eocen...
