Abstract The history of the study of the Sarmatian sections in the basin of the Belaya River is discussed and their lithology is described. The gastropods from beds with Cryptomactra pesanseris, except for their lowest part, are described. A description of some species from the Lower Sarmatian rocks embedded in the Middle Sarmatian olistostromes has also been added. As a result, 30 gastropod species from the families Lottiidae, Trochidae, Hydrobiidae, Nassariidae, Pyramidellidae, Cornirostridae, Acteocinidae, and Retusidae were identified. The new genera Edozeba and Pomatiasia (Hydrobiidae), new species Edrozeba angulata, E. caeca, E. minuta, E. striata, Hydrobia neofrauenfeldi, Akburunella laminaris, A. sinuosa, A. spinosa, Odostomia caucasica, and Brahystomia succineiformis; new subspecies Akburunella nefanda archaica and Cornirostra anistratenkorum umbilicaris have been identified. The Middle Sarmatian pyramidellids are reviewed and redescribed. The taxonomy and composition of the genera Kolesnikoviella (Trochidae) and Akburunella (Nassariidae), origin, morphogenesis, and composition of other described gastropod taxa are discussed. Statistical data on gastropod communities from the lower part of the beds with C. pesanseris are presented.
