Abstract

This paper presents the results of the study of the Upper Bajocian Garantiana garantiana Zone (Middle Jurassic) and characteristic ammonites in sections of the basin of the Kuban River (Karachay-Cherkessia). The assemblage contains species of the genera Garantiana, Pseudogarantiana, Paragarantiana, Djanaliparkinsonia (all family Stephanoceratidae) and Vermisphinctes (family Perisphinctidae). A section of the Garantiana Zone on the Kyafar River contains (from bottom to top) Beds with Djanaliparkinsonia alanica (also recognized on the Kuban River), Beds with Garantiana subgaranti and Beds with Paragarantiana, approximately corresponding to the Dichotoma, Garantiana, and Tetragona subzones of the standard scale. Garantiana subgaranti Wetzel and Vermisphinctes martiusii (d’Orbigny) are described. Prorsisphinctes Buckman, 1921 is proposed as a junior subjective synonym of Vermisphinctes Buckman, 1920.

摘要

本文介绍了上巴霍亚人Gar属（garantiana garantiana）带（侏罗纪中部）和库班河（Karachay-Cherkessia）流域部分特征性褐铁矿的研究结果。该组合包含Gar藤属，假ant藤属，巴拉D藤属，Djanaliparkinsonia属（所有Stephanoceratidae科）和Vermisphinctes属（Perisphinctidae科）的种。所述的部分Garantiana区上Kyafar河含有（从底部到顶部）与床Djanaliparkinsonia alanica（也认识到在库班河）中，用床Garantiana subgaranti并与床Paragarantiana，大致对应于标准规模的双歧杆菌、,属和四角形亚区。描述了Garantiana subgaranti Wetzel和Vermisphinctes martiusii（d'Orbigny）。Prossisphinctes Buckman，1921年被提议为Vermisphinctes Buckman，1920年的初级主观同义词。
