翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Palaeoxyris ： ウィキペディア英語版 Palaeoxyris ''Palaeoxyris'' is the prehistoric shark egg capsule morphotype of the family Hybodontidae with a predominant occurrence in ancient freshwater environments. They comprise a beak, a body and a pedicle, with the beak merging into the body. They display a conspicuous right-handed spiral of ridges around the body, and in some cases, the pedicle. Originally described as plant remains and controverselly discussed within the floral kingdom it took decades before their true nature as animal eggs was revealed. Nearly 30 different ''Palaeoxyris'' species are currently known with a stratigraphic range from the Carboniferous to the Cretaceous. One species, ''P. friessi'' was described in 2010, from Middle Triassic deposits at Ilsfeld, southern Germany.〔 Another, ''Palaeoxyris alterna'', was described in 2011 from lake deposits of the Middle Triassic Madygen Formation in Kyrgyzstan. ==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「Palaeoxyris」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.
