''Cadamoceras'' has smooth inner whorls but the outer has course plications on the outer (ventral) flanks and across the venter. The aperture has a large scoop-like rostrum and spatulate lappets flanking either side. The suture is straight with small, widely separated lobes. ''Cadamoceras'', named by Munier-Chalmas in 1892, is a member of the ammonitid family Haploceratidae which is part of the superfamily Haplocerataceae. ==References== * Treatise on Invertebrate Paleontology, Part L, Ammonoidea (L273) Geological Society of America and Univ of Kansas Press, 5th printing 1990. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cadomoceras」の詳細全文を読む スポンサード リンク
