| 摘 要： | 系统研究了鄂尔多斯盆地东北缘高头窑一带的中侏罗统延安组植物化石，18属31种。其组成特征表明，当前植物群属于典型的Coniopteris-Phoenicopsis植物群，其时代为中侏罗世。与植物群伴生的昆虫化石的研究提供了一致的时代意见。

| Abstract: | A Middle Jurassic flora consisting of 31 species of 18 genera from the Yan'an Formation of the Gaotouyao area in the northeastern margin of Erdos Basin is studied in detail for the first time. The flora indicates a typical Coniopteris-Phoenicopsis flora in floristic characteristics. The age of the present flora,considerded as Middle Jurassic,is evidenced by the study of its associated insect fossils also. |
