Baltic Amber, MCNA collection (Eocene of Russian Federation)

Where: Kaliningrad, Russian Federation (54.9° N, 19.9° E: paleocoordinates 53.9° N, 15.2° E)

• local area-level geographic resolution

When: Priabonian (38.0 - 33.9 Ma)

• According to Aleksandrova and Zaporozhets (2008), the higher parts of the Prussian Formation (including the Blaue Erde or Blue Earth) belong to the Charlesdowniea clathrata angulosa dinocyst Zone. Based on its index species, this zone is concurrent to Zone W13 established in the Parisian basin (Châteauneuf and Gruas-Cavagnetto 1978), where it is correlated with nannoplankton zones NP18–NP21 (Powell, 1992) of the Priabonian. In the Paleogene zonation of northwestern Europe, the first occurrence of Thalassiphora fenestrata is designated at the base of the dinocyst Subzone D12b (36.20 +/- 0.1 Ma), which is correlated with zones NP18 (terminal part)–NP20 of the Priabonian (Luterbacher et al., 2004).
