Trying to find a definitive identification for this nautiloid? Anyone know of any science-based paper online to refer to the Ma'der region of Morocco during this period of time and the cephalopod fauna? Any info appreciated. Devonian section in the Tafilalt, Ma'der region, Anti-Atlas, Morocco.
(Clymenia genus ammonoid? do they get this large and the chamber/whorls are very similar to nautiloids)
