| 摘 要： | 吉林南部杉松岗盆地早侏罗世植物群主要由松柏类、银杏类、真蕨类和茨康类组成，迄今已发现22属37种。其典型特征是锥叶蕨(Coniopteris)与准苏铁果(Cycadocarpidium)共生，显示了欧亚大陆早侏罗世植物群早期组合的特征，其地质时代似为早侏罗世早期。这一发现对确定杉松岗盆地含煤地层的地质时代和建立我国北方侏罗纪植物群序列具有重要的科学价值，对探讨吉林南部的地质发展史也具有重要的意义。

| Abstract: | More than 37 species of 22 genera of fossil plants are recognized by the authors from the Shansonggang Basin of southern Jilin, China, including mainly conifers, ginkgoales, ferns and czekanowskiales. The flora is characterized by the coexistence of Coniopteris and Cycadocarpidium , showing the characters of the early assemblage of Early Jurassic floras in Eurasia. Therefore, the Shansonggang flora is considered to be Early Early Jurassic in age. This study would be beneficial for determining the geological age of the coal-bearing strata in the Shansonggang Basin, making clear on the Jurassic floristic sequence of North China, and for sludying the geological evolutionary history of the southern Jilin. |
