''Anadesmoceras'' has a shell shaped more or less like a compressed ''Cleoniceras'' but with faint ornament only on the inner whorls. The shell has bundled growth striae. The aperture is preceded by several wide sinuous constrictions. ==References== Mesozoic Ammonoidea, Arkell ''et al''; Treatise on Invertebrate Paleontology, Part L. p.L394. 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「Anadesmoceras」の詳細全文を読む スポンサード リンク
