A compendium of updated Shallow Benthic Zones for the Paleogene and the Miocene

This work provides a complete update for both Shallow Benthic Zones (SBZ) and Orthophragminid zones (OZ) based on Cenozoic larger foraminifera, including the recently proposed SBP for the Paleocene. The proposed zonation considers the time span from Danian to Tortonian, thus including the entire Paleogene and part of the Neogene. According to the most recent literature, here we propose a correlation of shallow-water biozones with the established planktonic biozones, geomagnetic chronozones, and standard chronostratigraphy using the most recent Geological Time Scale (GTS), available from 2020. This study illustrates and describes all data used to tie each single SBZ and SBP to enable the correlation to the chronostratigraphic chart. The OZ boundaries have been moved accordingly, as they are defined based on their relationship with SBZ.
