Lithology description: "[Baitugan - Kamyshla Beds] Bed S5/6-1 Grey limestones with foraminifers, the marine gastropod Goniasma sp., and bivalves. The upper part of the limestones is characterised by very fine 'sheet' lamination and contains conchostracans, non-marine bivalves, mass accumulations of the charophytes Stellatochara gracilis, and the leaves and stems of various plants. The thickness is 0.8m. Bed S5/6-2 Siltstone: greenish-grey with Palaeomutela sp. The thickness is 0.15m. Bed S5/6-3 Limestone: grey, 'sheet' laminated, with Palaeomutela. The thickness is 0.8m. Bed S5/6-4 Coaly rock ('charcoal'). The thickness is 0.13m. Bed S5/6-5 Siltstone: greenish-grey. The thickness is 0.06m. Bed S5/6-6 Limestones and marls with Palaeomutela umbonata. The thickness is 0.2m. Bed S5/6-7 Siltstone: greenish-grey. The thickness is 0.4m. Bed S5/6-8 Limestone: grey, compact, with marine bivalves in the lower part. The upper part contains the bivalves Liebea (?) sp., many fish scales, and fragments of amphibian bones. The thickness is 0.6m. Bed S5/6-9 Sandstone: greenish-grey, with a shale seam in the upper part. The thickness is 0.5m. Bed S5/6-10 Limestone: grey, compact. The thickness is 0.2m. Bed S5/6-11 Siltstone: greenish-grey, with Palaeomutela umbonata. The thickness is 0.1m. Bed S5/6-12 Marl and limestone: grey, with a thin lamina of coaly rock and with Pseudomonotis permianus. The thickness is 0.35m. Siltstone: greenish-grey. The thickness is 0.2m." (Nurgaliev et al. 2015)
