They were similar to the nautiloid ''Michelinoceras'' in the apex, but had shorter necks to their septa that were orthochoanitic or suborthochoanitic.〔 〕 The sphaerorthoceratids were significant in cephalopod evolution because they may have given rise to the bactritids, which in turn were the ancestors of ammonoids and coleoids. The family lived in the middle Paleozoic, ranging from the Sheinwoodian age of the Silurian Period to the Famennian age of the Devonian Period, or about 428 to 361 Ma.〔(【引用サイトリンク】work= The Paleobiology Database )〕 ==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「Sphaerorthoceratidae」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
