Abhandlungen %V 165 %N 3 %X Three new genera of endocochleate cephalopods from the Lower Devonian cast new light on the evolution of modern and fos sil coleoids. Protoaulacoceras n. g. represents the r03trum-bearing line of aulacocerid-belemnitid type, while the ontogeny shows still features of the michelinoceratid ancestors. In contrast, Boletzkya n. g. and Naefiteuthis n. g., in which the chambered part of the shell looses its function during ontogeny, show a trend towards Mesozoic Loligosepiidae and recent teuthids. %U http://resolver.sub.uni-goettingen.de/purl?gldocs-11858/6873 %~ FID GEO-LEO e-docs
