Kurgan, south of (Eocene of Russian Federation)

Where: Russian Federation (56.3° N, 65.6° E: paleocoordinates 56.8° N, 60.3° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Tavda Formation, Priabonian (38.0 - 33.9 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; sandstone and claystone

• Tavda Formation in the section consists of two beds. The basal 0.4 meter of the sediments are turquoise non−calcare− ous clays, overlain by bright green non−calcareous clays with numerous beds and lenses of poorly−sorted glauconitic quartz sand. In the upper part of the bed there is a 0.7 meter thick lens of poorly−sorted sand, with phosphate pebbles and nodules in the top. This lens contains a huge number of shark teeth, as well as the bones of bony fish and marine mammals. The clays below and above this lens contains a dinoflagellate assemblage with Charlesdowniea clathrata angulosa indi− cating a Priabonian age.
