At the XIV International Palynological Congress and X International Organization of Palaeobotany Conference (Salvador, Brazil, 2016) W. M. K. Matsumura, N. M. Balzaretti, and R. Iannuzzi demonstrated a poster entitled "Fourier transform infrared spectrosopy of Spongiophyton (Spongiophytaceae) frpm the Middle Devonian of Parana Basin, Brazil". Now I am stadying compressions of similar plants from the Devonian of Russia by the same method. So I am very interested to find out whether their results were published in more details.
