Their shells were very similar to the related ammonites of the genus ''Ainoceras'', where the young ammonite's shell coiled helically, and upon reaching adulthood, the youngest coil arched over the older coils. ==References== 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「Anaklinoceras」の詳細全文を読む スポンサード リンク
