Artinskian (Early Permian) Sea Basin and Its Biota (Krasnoufimsk, Cis-Urals)

— This work presents the study history of the Artinskian deposits in the area of the town of Krasnoufimsk (Sverdlovsk oblast) and its environs, where the stratotype sections of the Divjinskian and Sarginskian formations of the upper Artinskian substage are exposed. The sections of Krasnoufimskie Klyuchiki, After Selection, Sobolya, etc., are described in detail; the data on assemblages of fossil remains identified in each of the sections are given. The taphonomic observations are outlined and a paleoecological reconstruction of the Sarginskian ecosystem of the Krasnoufimsk area is proposed.
