Abstract

The coprolite containing conchostracans from the terminal Permian Bykovka locality of Vyaznikovian tetrapod faunistic assemblage (the east of the Vladimir Region, Russia) are described for the first time. The most likely producers of such coprolites might be seymouriamorphs belonging to the genus Microphon, currently discovered in this locality. The composition of the conchostracan assemblage provides additional independent biostratigraphic confirmation of the highest position of Bykovka locality in the Permian interval of the Vyazniki section.

与俄罗斯中部二叠纪末二叠纪的蛇纹石共生—古生物学和地层学意义

摘要

首次描述了来自Vyaznikovian四足动物组合（俄罗斯弗拉基米尔地区东部）末端二叠纪Bykovka地方的共生腐殖质。这种共proprolites的最可能生产者可能是属于Microphon属的seymouriamorphs ，目前在该地区发现。conchostracan组合的组成为在Vyazniki断层的二叠纪中Bykovka局部的最高位置提供了额外的独立生物地层学确认。
