Abstract
Permian ray-finned fishes from freshwater deposits of the Leninsk (Tatarian Series, Severodvinian Stage) and the Tailugan Formations (Tatarian Series, Vyatkian Stage) of Kuznetsk Basin are revised. The taxa considered in the work were not previously formally published and remained nomina nuda. Two new genera (Gregarialepis and Planalepis) and two new species (G. binaria and P. diserta) are described. Scales of Heterolepis undata (reidentified cf. Eurynotoides sp.), Mitinolepis surickovensis (reidentified Strelnia sp.), are too poorly preserved, the available features are not sufficient to distinguish new taxa, and they can only be identified to genus-level.
期刊介绍：
Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
