摘要

摘要对库兹涅茨克盆地列宁斯克地层（塔塔里亚系，塞维鲁德维尼期）和泰卢根地层（塔塔里亚系，维亚特克期）淡水沉积中的二叠纪鳐形鳍鱼类进行了修订。工作中考虑的分类群以前未正式发表过，仍然是nominina nuda。描述了两个新属（Gregarialepis 和 Planalepis）和两个新种（G. binaria 和 P. diserta）。由于 Heterolepis undata（重新鉴定为 Eurynotoides sp.）、Mitinolepis surickovensis（重新鉴定为 Strelnia sp.）的鳞片保存太差，现有特征不足以区分新类群，只能鉴定为属级。

Revision of Permian Ray-Finned Fishes from the Leninsk and Tailugan Formations of the Kuznetsk Basin

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.
