Abstract:
The palynological study of the cores from the borehole 20 at Dabuleni allowed identification of richmicrophytoplanktonic assemblages. The deposits investigated palynologically were dated as Bartonian-Priabonian of Eocene,yielding abundant dinoflagellate assemblages, which involve Areosphaeridium diktyoplokus, Enneadocysta multicornuta,Batiacasphaera compta, Deflandrea phosphoritica, D. leptodermata, Hystrichokolpoma cinctum, Impagidinium sp., I.maculatum, Palaeocystodinium golzowense, Rhombodinium rhomboideum, Samlandia chlamydophora, Spiniferites ramosus,Thalassiphora pelagica, Wilsonidium compactum etc. Two new species and one genus of dinoflagellate cysts are describedfrom this Bartonian-Priabonian interval. They are Chateauneufacysta moesica gen. et sp.nov. and Rhombodinium antonescuisp. nov.
