Most ''Pecopteris'' leaves and fronds are associated with the marattialean tree fern ''Psaronius''. However, ''Pecopteris''-type foliage also is borne on several filicalean ferns, and at least one seed fern. 〔Taylor, Thomas N. & Edith L. Taylor. ''The Biology and Evolution of Fossil Plants'', page 598. (Englewood Cliffs, NJ: Prentice Hall, 1993). ISBN 0-13-651589-4.〕 Pecopteris first appeared in the Devonian period, but flourished in the Carboniferous, especially the Pennsylvanian. Plants bearing these leaves went extinct in the Permian period. == Etymology == ''Pecopteris'' is derived from the Greek ''pekin'', (to comb), and ''pteris'', (a fern).〔Webster's New Universal Unabridged Dictionary, Simon & Schuster Publishing, 1972. ISBN 0-671-41819-X.〕 This is because the leaflets of ''Pecopteris'' fronds are arranged like the teeth on a comb.〔Webster's Third New International Dictionary, Volume II, 1976, pg. 1662.〕 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「Pecopteris」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.
