Abstract

Eleven imprints of chiton valves from the Sakmarian of the Shakhtau reef massif (Bashkir Cis-Urals) are assigned to a new species Ochmazochiton uralensis sp. nov. Previously, the genus Ochmazochiton was known only from the type species described from the Lower and Middle Permian of Texas. Due to the unique preservation of the studied material, the structure of the aesthete pores is shown for the first time, and the structure of the insertion plates, the important morphological characters of the genus Ochmazochiton, the earliest representative of the order Chitonida, is clarified.

来自 Shakhtau（南西乌拉尔）下二叠统礁石灰岩的 Ochmazochiton 属（软体动物，多孔动物）新物种

摘要：来自Shakhtau珊瑚礁群（Bashkir Cis-Urals）Sakmarian岩层的七鳃鳗瓣膜印迹被归入一个新种Ochmazochiton uralensis sp.nov.。在此之前，Ochmazochiton 属仅见于德克萨斯州中下二叠统的模式种。由于所研究材料的独特保存方式，首次显示了美齿孔的结构，并明确了插入板的结构，这是甲壳纲最早的代表--Ochmazochiton 属的重要形态特征。
