The first finding of foraminifera in Ludlowian carbonate rocks at the Ilych river

The results of a microscopic study of the Upper Silurian carbonate rocks in the Ilych River (Northern Urals) have been represented in the article, which revealed primitive foraminifera for the first time. The description of paleontological material and distribution of foraminifera in the section was given. A total of 11 genera and 12 species of foraminifera were found. The study of Late Silurian foraminifera expanded the geography of distribution of Chitinolagena, Ordovicina and stratigraphic genera of the following species: Bisphaera primitive , B. ex gr. obscur a, Parastegnammina cf. grandissima , Baituganella sp., Cribrotuberitina insueta . The most numerous representatives were foraminifera of genus Caligella among which the forms found in the carbonates of outcrop 112, were different in size compared to the specimens from reef limestone outcrops 110 and 111, which could probably be connected with unfavorable continental slope conditions.
