Their fossils are known from South Africa, Australia, New Zealand, South America and Antarctica. They were first discovered in Triassic sediments of Tasmania by Morris in 1845.〔http://www.qm.qld.gov.au/~/media/Documents/QM/About%20Us/Publications/Memoirs%20-%20Nature/N52-2/52-2-anderson-et-al.pdf〕 == Description == The leaves were essentially like those of modern ferns however they were forked; giving the appearance of two fern leaves joined at the base. It seems that they were deciduous trees. These plants had male and female reproductive structures. Before awareness that they belonged to the same species, male pollen-bearing specimens were named ''Pteruchus'' and the female structures ''Umkomasia''.〔http://www.fossilmuseum.net/plantfossils/Umkomasia/Umkomasia.htm〕 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「Dicroidium」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.
