Cenozoic cyclostomatous bryozoans from the Qom Formation (Chahriseh area northeast of Isfahan, central Iran)

The Dizlu and Bagh Sections in the Oligocene - early Miocene Qom Formation (northeast of Isfahan, central Iran) has yielded a rich association of Bryozoa including eleven species belonging to the order Cyclostomata. The description of these eleven species (including three new species (Exidmonea baghi sp.n., Nevianipora isfahani sp.n. and Polyascosoecia iranica sp.n.) increase the knowledge with respect to the faunal diversity within the Qom Formation.
