Description
Summary:Fig. 16. Reconstruction and interpretation of details of connecting ring and septal necks in rioceratid cephalopods from the Olenidsletta Member, Floian, Ordovician, Profilstranda section, Ny Friesland, Spitsbergen. A. Ethanoceras solitudines gen. et sp. nov., FMNH-P30406, see Fig. 15B. B. Svalbardoceras skua gen. et sp. nov., FMNH-P30274, see Fig. 23F. C–D. Svalbardoceras sterna gen. et. sp. nov., note variability of septal neck shape, which is interpreted as an effect of poor preservation. C. Specimen, FMNH-P30368, see Fig. 23G. D. Specimen, FMNH-P30371, see Fig. 23E. Black: septal neck and septum. Dark grey: connecting ring. Without scale.
