Geologicheskii Vestnik

The article characterizes subfossil terrestrial and freshwater molluscs of the territory of the Bashkir shikhans of Yuraktau, Kushtau and Toratau (Toratau geopark), which are regional natural monuments and are nominated for UNESCO status. For the first time, the species composition of terrestrial molluscs living on the slopes and at the foot of the Early Permian reef massifs, as well as freshwater molluscs in oxbow lakes and lakes at the foot of shikhans was established. A total of 52 species were recognized: among them — terrestrial mollusсs are represented by 28 species, freshwater — by 24 species. Among terrestrial molluscs, the communities confined to rocks and steppe slopes are the richest in terms of species and quantity of shells, which indicate a close relationship of calcephilous mollusсs with a carbonate substrate, as well as exposure of slopes. The description of molluscs’ complexes according to biotopes is given.
