Аннотация:A scale of Discordichthys spinifer is described from the Upper Kazanian (Guadalupian) freshwater deposits of Sidorovy Gory-2 locality, on the right bank of the Kama River (Votkinsk District, Udmurt Republic, Russia). This is the first record of discordichthyiform fish in the Kazanian, which supports a wide stratigraphic distribution of this group in the Middle and Upper Permian (Biarmian and Tatarian) of the East-European Platform. A new synonymy is established: Mutovinia stella Minikh, 1992 = Mamulichthys ignotus A. Minikh, 2014, syn. nov.
