Description
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.
