Аннотация: We describe the findings of cyclidans from the unpublished collection of the famous paleontologistB.I. Chernyshev (1888–1950) in the storage of the Academician F.N. Chernyshev CentralScientific Research Geological Survey Museum (CNIGR museum, St. Petersburg, Russia). Thesecyclidans were discovered by various researchers in the Carboniferous and Permian of the Urals.They are represented by the following taxa: Oonocarcinus uralicus new species, Uralocyclusfeldmanni new species, Ambocyclus capidulum (Chernyshev, 1933), and Magnitocyclus (?)sp. indet. The discovery of the new species Oonocarcinus uralicus n. sp. greatly expands thegeographic and stratigraphic interval of the genus Oonocarcinus Gemmellaro, 1890, previouslyknown from the Middle Permian and Triassic. The discovery of Uralocyclus feldmanni n. sp. inthe Mississippian deposits of the Chelyabinsk Oblast indicates a wide distribution of the genusUralocyclus Mychko and Alekseev, 2018 in the Early Carboniferous, because Carboniferousrepresentatives of this genus were previously known only from Ireland and England. The paperprovides an up-to-date list of all known cyclidan occurrences and taxa in Russia.
