Abstract

New finds of cephalopod jaw apparatuses from the upper part of the Niortense Zone and the lower part of the Parkinsoni Zone (Upper Bajocian) from the interfluve of the Kuban and Urup rivers (Northern Caucasus) are described. Two isolated valves of aptychi which are considered to be ammonoid lower jaws are assigned to the superfamilies Haploceratoidea and Stephanoceratoidea. Two upper jaws likely belonged to ammonites with aptychus-type jaw apparatus (Ammonitida). The seven anaptychus-type jaws are assigned to the orders Phylloceratida and Lytoceratida. A well-preserved upper jaw of coleoid affinity is described for the first time from the Mesozoic of the Northern Caucasus.

北高加索地区上侏罗统（中侏罗统）的头足类颚动物的新记录（俄罗斯，卡拉恰伊-切尔克斯西亚）

摘要

从上部头足类动物爪装置的新发现Niortense区和下部Parkinsoni从库班和得抚河流的分野（北高加索）区域（上部巴柔）中有所描述。将两个孤立的aptychi阀（被认为是下颌类的下颌）分配给超家族Haploceratoidea和Stephanoceratoidea。两个上颚可能属于具有aptychus型颚式器械（Ammonitida）的炸药。七个反突颚型颚被指定为Phylloceratida和Lytoceratida。从北高加索地区的中生代以来首次描述了保存完好的类固醇亲和力的上颚。
