title: Integrated Biostratigraphy of Eocene Deposits in the Gubs Section (Northern Caucasus) with special Attention to the Ypresian/Lutetian Boundary and to the Peritethyan-Tethyan Correlation
abstract: The Ypresian to Priabonian Gubs river section, in the Adygean high of the northern slope of the Caucasus, is a rare locality, in whichYpresian-Lutetian representative larger benthic foraminifera coexist with planktonic Foraminifera and calcareous nannoplankton. This provides a good opportunity to apply and refine the zonal Ypresian-Lutetian scheme of the Crimean-Caucasus region, to correlate the zonal subdivision of the three most important Palaeogene groups of microfossils and to give a new ins
