摘要
南黄海CSDP-2钻井上泥盆统五通组擂鼓台段2 068.00～2 069.02m段岩心识别出了早期真蕨类植物。该植物具有至少三次羽状复叶,末二次羽片互生,小羽片扁平,呈扇状、楔状或舌状,基部收缩,至少一次深裂,裂片边缘钝圆,二分叉的叶脉明显。据此,可鉴定为优美守刚蕨(比较种)(Shougangia cf.S.bella)。本研究为南黄海地区上泥盆统五通组增加了古植物学新资料。
A fern-like plant is identified at 2 068.00-2 069.02 min the borehole of the Well CSDP-2of South Yellow Sea which belongs to the Upper Devonian Leigutai Member of Wutung Formation.The plant consists of at least three-time pinnate compound leaves,the secondary rachises are alternately attached,and the ultimate pinnule is planar and fan or wedged shaped with a contracting basal part.The pinna has at least one deep lobe with blunt margins and has conspicuous bifurcate veins.Accordingly,the plant is classified to Shougangiacf.S.bella.The study adds new palaeobotanical data for the Upper Devonian Wutung Formation in South Yellow Sea.
