Fossils
The lower part of the formation yields buchiid bivalves Aucellina aptiensis and A. caucasica (Turbin, 1994; Markevich et al., 2000) typical for the Aptian-Albian in many regions of the Earth (Zonova and Yazykova, 2004), whereas the middle part is in addition characterized by ammonites Acanthohoplites aschiltaensis, A. cf. spathi, A. ex gr. abichi and Parahoplites sp. (Turbin, 1994; Markevich et al., 2000) suggesting an upper Aptian range of the rocks
