Baltic amber, Konigsberg collection (Eocene of Russian Federation)

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

When: Priabonian (37.2 - 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).

Environment/lithology: terrestrial; amber

Size classes: macrofossils, mesofossils

Preservation: amber

Collection methods: Collection in the Amber collection (Bernsteinsammlung) of the University of Königsberg. Some comes from the Stantien and Becker collection (S.B.), partners who formed a business in 1860 to mine Baltic amber. The Stantien and Becker collection was originally at Konigsberg and was feared to be lost but it was divided (in part) among various museums. The ultimate repository of these S.B. specimens is unknown. Other material is in the collection of the Physilakisch-okonomischen Gesellschaft (P.O.). Many of the surviving specimens are in Gottingen.
