Abstract

Upper Tithonian to lower Berriasian carbonate sequence of the Getic Nappe System was studied near Golubac using an integrated biostratigraphy approach based on calpionellid, calcareous dinoflagellate, nannofossil, foraminifer, and palynomorph record. Calpionellids allowed subdivision of the section to standard calpionellid zones including the Colomi and Alpina subzones on the Tithonian–Berriasian transition. Nannofossil Nannoconus wintereri proves the presence of the NC0 Zone. Foraminifer fauna on the Tithonian–Berriasian transition contain zonal marker Globospirillina neocomiana and some other potential stratigraphic markers, whose range and taxonomy have to be fixed yet. Poor palynomorph spectra consist of long-ranging Lower-Cretaceous spores and pollen, and a few dinoflagellate cysts known from the Berriasian. Integrated biostratigraphy of the Tithonian–Berriasian oligotrophic open-marine carbonate facies of the Dedina section contributes to the stratigraphic framework necessary for the definition of the Berriasian Global Boundary Stratotype Section and Point.
