Miocene ostracods of Chuya and Kurai depressions of the southeastern Altai

Аннотация

Ostracods from the lacustrine–alluvial beds of intermontane troughs of the Altai Mountains are examined. Ostracods similar in species composition are recorded in the Lower–Middle Miocene of southeastern Kazakhstan. Changes in species composition and abundance of ostracods in the section of boreholes caused by changes in paleogeographical conditions of water bodies are analyzed. A new species of the genus Candona is described. For the previously known ostracod species, figures are provided.
