LATE VISéAN LYGINOPTERIDOPHYTES FROM THE VICINITY OF THE TOWN OF BOROVICHI (NOVGOROD REGION): 2. LYGINOPTERIDALES AND MEDULLOSALES

Abstract

Five lyginopteridalean species of the genera Rhodeopteridium (Zimmermann) Purkynová and Sphenopteris Brongniart and one species of Rhynchogonium Heer (Medullosales=Trigonocarpales) are reported from the vicinity of the town of Borovichi (Upper Viséan deposits) for the first time. Rhodeopteridium goeppertii (Ettingshausen) O. Orlova et S. Snigirevsky comb. nov. is proposed. The study has revealed a rich preridospermous assemblage that characterizes the Early Carboniferous flora of the northwest of the Moscow Syneclise.
