Abstract

This paper contains the first descriptions of an assemblage of non-ammonoid cephalopods from the Upper Asselian-Lower Sakmarian limestones of the Shakh-Tau reef. In this paper 16 species of 15 genera belonging to orders Oncocerida (?) and Nautilida (suborders Nautilina and Liroceratina), of which seven genera and 13 species are new, are described. Two species are described in open nomenclature. Representatives of the order Oncocerida (?), as well as the nautilids of the genera Temnocheilus and Megaglossoceras, were found for the first time in the Early Permian (until now it was believed that they became extinct in the Carboniferous).

摘要

本文首次描述了沙赫-塔克礁的上阿瑟利安-下萨克曼石灰岩中的非铵类头足类动物。在本文中，描述了属于Oncocerida（？）和Nautilida（Nautilina和Liroceratina子亚目）的15个属的16种，其中7个属和13个是新的。公开术语中描述了两种。在二叠纪早期首次发现了Oncocerida（？）纲的代表以及Temnocheilus和Megaglossoceras的鹦鹉螺（直到现在人们认为它们已在石炭纪灭绝了）。
