The faunas include 54 species, of which two are new, Streblotrypa (Streblotrypa) peculiaris sp. nov. and Bashkirella minor sp. nov. Bryozoans are represented mainly by fenestrates (27 species), followed by rhabdomesine cryptostomes (eleven species), cystoporates (ten species) and trepostomes (six species). Some species were known previously from the Pennsylvanian of northern Spain and the Carnic Alps, others from the Carboniferous of the Russian Platform and North America.
