Calamitaceae is an extinct family of plants related to the modern horsetails. Some members of this family attained tree-like stature during the Carboniferous Period (around ). The family takes its name from its principal genus ''Calamites''. Because some proposed species are based on partial fossil records, it is not clear if these are merely different parts of the same type. == Proposed genera and species of Calamataceae == * ''Annularia''. * * ''A. stellata''. * ''Arthropitys''. * ''Asterophyllites'' (or incorrectly ''Asterophyllum''). * ''Astromyelon''. * ''Calamites''. * * ''C. carinatus''. * * ''C. suckowi''. * * ''C. undulatus''. * ''Calamocarpon''. * ''Calamostachys''. * * ''C. binneyana''. * ''Cingularia''. * ''Mazostachys''. * ''Paleostachya''. 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「Calamitaceae」の詳細全文を読む スポンサード リンク
