• "[Upper Kazanian Substage - Belebey Formation (continuation)]

•Package S2/9 Interval 93.5 - 109.5m Thickness 16.0m

•Sandstone: brownish-grey, obliquely laminated, with lenses of basal conglomerates overlying the eroded surface of the Lower Kazanian rocks. Solid calcareous sondstones form rocky ledges that are well traced along the slope. Horizontally, sandstone is replaced with sandy-muddy succession, and its thickness ranges from 2m to 15m.

•Package S2/10 Interval 109.5 - 119.5m Thickness 10.0m

•Siltstone and shale with one-two laminae (0.3-0.5m) of limestone. Siltstone and shale: red, reddish-brown, pinkish-red, calcareous, with green spots of gleisation and calcareous concretions (paleosol horizons). Limestone: dark- and light-grey, muddy, compact, solid, algal-microbial, sometimes very hard and finely wavy laminated, riddled with numerous voids of plant roots in situ. Shales underlying the upper limestones bed contain non-marine bivalves, ostracods and fish scales.

•Package S2/11 Interval 119.5 - 131.5m Thickness 12.0m

•Shales and siltstones with thin (up to 0.3m) rare marl and limestone laminae. Siltstone and shale: red, reddish-brown, calcareous, with green spots of gleisation and calcareous concretions (paleosol horizons). Marls: grey, greenish-grey, cream-coloured, massive, silty and sandy. Limestone: dark- and light-grey, muddy, compact, solid, algal-microbial, sometimes very hard and finely wavy laminated, riddled with numerous voids of plant roots in situ. In the top, the shale overlying the upper limestone contain non-marine ostracods, bivalves and fish scales.

•Package S2/12 Interval 131.5 - 141.5m Thickness 10.0m

•Shales, siltstones and sandstones. Siltstone and shale: red, reddish-brown, calcareous, with green spots of gleisation and calcareous concretions (paleosol horizons). Sandstone: brownish-red, wavy laminated. At the top, the package contains a bed (0.2-0.6m) of light-grey algal-microbial limestone riddled with numerous voids of plant roots in situ. Shales subjacent to limestone surfaces contain non-marine ostracods, bivalves and fish scales.

•Package S2/13 Interval 141.5 - 159.0m Thickness 17.5m

•Sandstones and siltstones with rare thin (0.2-0.3m) laminae of marl. Sandstones and siltstones: reddish-brown, calcareous, with green spots of gleisation and calcareous concretions (paleosol horizons). Marls: grey, greenish-grey with red spots of gleisation. At the top of the package, the succession contains a lens of brownish-red siltstone (0.5m) with non-marine bivalves, ostracods, fishes and tetrapods.

•Packages 9 and 10 are tentatively assigned to the Prikazan Beds, package 11 to the Pechishchi Beds, package 12 to the Verkhnyi Uslon Beds, and package 13 to the Morkvashi Beds." (Nurgaliev et al. 2015)
