Fossils

The lower part of the formation is characterized by a lower Albian faunistic assemblage including Aucellina cf. caucasica, A. cf. aptiensis, Inoceramus cf. anglicus, I. ex gr. anglicus, Tetragonites ex gr. timotheanus, Grantziceras cf. affine (Turbin, 1994; Markevich et al., 2000). The upper part of the formation yields Anagaudryceras? ex gr. aurarium, Puzosia sp., Subarcthoplites? sp. ind. and Gastroplites sp. (Turbin, 1994; Markevich et al., 2000).
