This paper reviews the foraminiferal biostratigraphy of the Devonian–Carboniferous (D–C) boundary beds in Russia and Western Kazakhstan. The regional records of the zonal successions of Russia are summarised from sections and boreholes of the Volga-Urals Subregion of the East European Platform (Syzran no. 401 Borehole, Melekesskaya no.1 Borehole); Timan-Pechora Province of the East European Platform (Kamenka Section); South Urals (Sikaza, Zigan, Ryauzyak and Dzerzhinka sections); Middle Urals (Pershino Section); and West Siberia, Vagai-Ishim Basin (Borehole no. 1 Kurgan-Uspenskaya), and the zonal successions of Western Kazakhstan are summarised from the Mugodzhary Mountains. Three foraminiferal biozones can be defined in the interval comprising the latest Devonian and earliest Carboniferous: Quasiendothyra kobeitusana Zone, the Tournayellina pseudobeata – remnant Quasiendothyra Zone, and the Earlandia minima Zone. The D–C boundary interval is situated within the Tournayellina pseudobeata–remnant Quasiendothyra Zone. A correlation with the ammonoid and conodont zonations is proposed, which is useful for correlating deep-water and shallow-water successions.

本文回顾了俄罗斯和哈萨克斯坦西部泥盆纪-石炭纪（DC）边界层的有孔虫生物地层学。从东欧平台的伏尔加河-乌拉尔次区域（塞兹兰401号井眼，迈利克斯卡斯卡亚1号井眼）的剖面和井眼中总结了俄罗斯地层演替的区域记录。东欧平台的蒂曼-佩乔拉省（Kamenka区）；南乌拉尔（Sikaza，Zigan，Ryauzyak和Dzerzhinka部分）；中乌拉尔（Pershino科）; 从Mugodzhary山脉总结了西西伯利亚，Vagai-Ishim盆地（钻孔编号1 Kurgan-Uspenskaya）以及哈萨克斯坦西部的带状演替。可以在区间内定义三个有孔虫生物区，包括最新的泥盆纪和最早的石炭纪：Quasiendothyra kobeitusana区，Tournayellina pseudobeata区-残余Quasiendothyra区和Earlandia minima区。D–C边界区间位于Tournayellina pseudobeata –残留的准西索德勒带内。提出了与氨水和牙形石带的相关性，这对关联深水和浅水演替很有用。
