翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Discosorus ： ウィキペディア英語版 Discosorus ''Discosorus'', a genus of the Discosorida and member of the family Discosoridae. Not to be confused with ''Discoceras''. ''Discosorus'' consists of rapidly expanding endogastric brevicones, mostly known from isolated siphuncles composed of broadly expanded segments that increase rapidly in size. Septal necks are recumbent, connecting rings thin, bullettes small. The siphuncle interior is occupied by endocones produced by layered annular deposits expanded back toward the apex, leaving a central tube running down the middle. The short phragmocone is poorly known. ''Discosorus'' is found in the Middle Silurian of eastern and arctic North America and as part of the Discosoratidae is derived from the Lowoceratidae which forms a link in the Early Silurian from the Late Ordovician exogastric ''Faberoceras'' of the Westonoceratidae. ==See also== *List of nautiloids 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「Discosorus」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.
