罗马尼亚Dabuleni地区钻井岩芯的孢粉学研究揭露了一些丰富的微体浮游植物组合。根据孢粉学资料确定为始新世Bartonian-Priabonian期的地层产有丰富的沟鞭藻组合,包含Areosphaeridium diktyoplokus,Enneadocystamulticornuta,Batiacasphaera compta,Deflandrea phosphoritica,D.leptodermata,Hystrichokolpoma cinctum,Impagidiniummaculatum,I.sp., Palaeocystodinium golzowense,Rhombodinium rhomboideum,Samlandia chlamydophora,Spiniferitesramosus,Thalassiphora pelagica和Wilsonidium compactum等。文中描述Bartonian-Priabonian期的沟鞭藻一新属两新种:Chateauneufacysta moesica gen.et sp.nov.和Rhombodinium antonescui sp.nov.。
Pollen studies of drilling cores in the Dabuleni area of Romania have revealed some rich assemblages of phytoplankton. Based on the palynological data, it was confirmed that the Eocene Bartonian-Priabonian formation is rich in dinoflagellates, including Areosphaeridium diktyoplokus, Enneadocystamulticornuta, Batiacasphaera compta, Deflandrea phosphoritica, D. leptodermata, Hystrichokolpoma cinctum, Impagidinium maculatum, I.sp. , Palaeocystodinium golzowense, Rhombodinium rhomboideum, Samlandia chlamydophora, Spiniferitesramosus, Thalassiphora pelagica and Wilsonidium compactum and the like. Two new species of Bartonian-Priabonian period dinoflagellates are described: Chateauneufacysta moesica gen.et sp.nov. And Rhombodinium antonescui sp.nov.
