Summary: | Genus Catoraphiceras Ulrich & Foerste, 1936 Type species Catoraphiceras lobatum Ulrich & Foerste, 1936; probably from the Powell horizon (late Floian–early Dapingian Stage), Wells Creek basin, northeast of Erin, Tennessee, USA; by original designation. Diagnosis Annulated orthocones whose sutures form ventral lobes; cross section is depressed to circular; siphuncles are moderately large (rSD = 0.25–0.35) and somewhat removed from the venter; septal necks are short; connecting rings are thin; some species develop ventral rods and cameral deposits (adopted from Hook & Flower 1977). Remarks The genus was previously placed within the Protocycloceratidae. : Published as part of Kröger, Björn & Pohle, Alexander, 2021, Early-Middle Ordovician cephalopods from Ny Friesland, Spitsbergen - a pelagic fauna with Laurentian affinities, pp. 1-102 in European Journal of Taxonomy 783 (1) on page 46, DOI: 10.5852/ejt.2021.783.1601, http://zenodo.org/record/5793422 : {"references": ["Hook S.
