New data on the planktonic foraminifers from the Yunusdag Formation (Coniacian–Santonian) in the Kelevudag Section, northeastern Azerbaijan

Аннотация

An assemblage of planktonic foraminifers is recognized for the first time from the Yunusdag Formation (Kelevudag Section, northeastern Azerbaijan) The analysis of foraminifers from the studied sample suggests that it may belong to the upper part of the Marginotruncana coronata Zone, embracing the interval from the upper Turonian to the lower Coniacian inclusive. The taxonomic composition of the assemblage allows the Kelevudag section to be assigned to an intermediate province separating the Boreal and Tethyan realms and including the Late Cretaceous carbonates of Dagestan.
