FL125 Calamites Stem Fossil
名稱 蘆木屬莖幹化石Name Calamites stem fossil地質年代 石炭紀Geological Age Carboniferous描述 蘆木屬是已絕種的高大的樹狀蕨類,和現代的木賊屬是近親。生長在潮濕的沼澤地帶中。在石炭紀時頗為興盛,和鱗木、封印木等一同形成廣大的蕨類雨林。它們的高度可達30公尺。其遺骸在地底下經長久的化學及物理作用後,形成現代人類最重要的燃料資源煤炭及天然氣。Description Calamites is a genus of extinct arborescent (tree-like) horsetails to which the modern horsetails (genus Equisetum) are closely related. Unlike their herbaceous modern cousins, these plants were medium-sized trees, growing to heights of more than 30 meters (100 feet). They were components of the understories of coal swamps.地點 蘭開夏,英國Location Lancashire, U.K.參考 Reference https://en.wikipedia.org/wiki/Calamites編者 由卓志鵬博士於7/4/2020編寫 _________ 於17/1/18最後編改 Editor Created by Dr. Chuck Chi Pang on 7/4/2020 Last modified by ________ as on 17/1/2018
