The foraminiferal assemblages from the Lower Permian deposits of the Toratau, Kushtau, and Yuraktau reef massifs were studied. Their taxonomic composition was determined taking into account the data published by previous researchers. A main feature of the foraminifera’s assemblages (fusulinids and small foraminifers) of Bashkir shikhans is the unique mixed composition of associations. Foraminiferal assemblages contain taxa both widely laterally distributed and endemic, both species of northern water areas and species of the Paleotethys area. The taxonomic composition of foraminifera is rich and varied, including more than 50 genera and more than 180 species. A brief description of the stratigraphic confinement of certain genera and species of foraminifers in the Asselian-Artinskian deposits that make up reef massifs is given, as well as basic information about the conditions and lifestyle of foraminifers.
