Paleozoic Bryozoa are reported from Severnaya Zemlya for the first time. Bryozoans of the orders Cystoporata Astrova, 1964 and Trepostomata Ulrich, 1882 are represented by four species, one of which is new: Halloporina severozemelica n. sp. from the Middle Ordovician. Representatives of the genus Fistulipora McCoy, 1849 from the Lower Devonian (Rusanov Formation) are similiar to the species F. nordica L. Nekhorosheva, 1961 from Taribigai Beds (Emsian) of Taimyr. Fistulotrypa<:i> sp. A from Rusanov Formation is the oldest species of the genus. The Permian species Dyscritella cf. lucida Morozova, 1986 has strong affinities with D. lucida from the Kapp Starostin Formation of Svalbard.
