 Drepanoistodus suberectus (Branson & Mehl, 1933) from the Mójcza Limestone. Diagnoza The sp elements with a weakly separated external area, pi elements flat with a somewhat elongated external tip of the base and a concave posterior side. Porównanie The apparatus composition was recognized by BERGSTROMand SWEET ( 1966) . Distinctions between the species and its predecessor, D. basiovalis, are somewhat problematic and additional biometric studies are necessary to clarify the issue. It remains far from clear whether the Late Ordovician populations from the North American Mid continent are conspecific with the European ones . Somewhat arbitrarily I assign to the species late populations of Drepanoistodus in the Mójcza section, starting from the discontinuity surface .
