Lithology description: Tavda Formation in the section consists of two beds. The basal 0.4 meter of the sediments are turquoise non-calcareous 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 indicating a Priabonian age.
Environment:marine indet.
