Abstract
The conodont succession in the Upper Devonian facially different sections of northeastern European Russia (Chernyshev Ridge, Subpolar and Polar Urals, Pai-Khoi) are studied. The sections are subdivided and correlated taking into account the global standards for stages. The Frasnian Montagne Noire zonation (Klapper, 1989) is used for the first time for northeastern European Russia; the authors correlated this zonation with the scale of Ziegler and Sandberg (1990). Famennian deposits are subdivided using scale of Ziegler and Sandberg (1984) and miospore zonation. The age of local geological units (formations) is specified; the formations of different regions of northeastern European Russia are correlated to each other and to the regional subdivisions of EEP and Southern Urals. A total of 93 species of Ancyrodella, Mesotaxis, Palmatolepis, Polygnathus, and Zieglerina are described. Two new species Ctenopolygnathus parallelus sp. nov. and Polygnathus masonae sp. nov. are distinguished and five species are described in the open nomenclature. Special chapter is devoted to the phylomorphogenesis of Ancyrodella.
