REVISION OF LIORHYNCHUS TAIMYRICUS NALIVKIN, 1936 (BRACHIOPODA; CAMAROTOECHIDAE) FROM THE FRASNIAN OF THE RUSSIAN ARCTIC

Abstract

The interior of Liorhynchiis taimyricns is studied. Consideration of its internal and external features suggests its assignment to the genus Caiyorhynchus Crickmay, 1952. A new subspecies Lateralatlmstrum atliabascensis (Kindle, 1924) iniloradovichi subsp. nov. and a new species Stenoinetoporhynchus novosemelicns sp. nov. are also described.
