| 摘 要： | 根据产于黑龙江鸡西早白垩世城子河组一种侧羽叶属(Pterophyllum)植物化石的外形特征及表皮构造研究,确认该种属于本内苏铁类(Bennettitales)植物,并有别于其他植物类群。据此,新建一新种—城子河侧羽叶(新种)Pterophyllumchengzihensesp.nov.,并讨论了该新种在研究中国东北地区早白垩世植物化石中的意义。

| Abstract: | Based on the external and cuticular structures of Pterophyllum leaves from Early Cretaceous Chengzihe Formation of Jixi coal-bearing basin in eastern Heilongjiang,and on the difference of the species from other known taxa mainly in cuticular characters,a new Bennettitalean species is recognized,and named Pterophyllum chengzihense sp.nov.The author discusses the significance of the finding of the new species for study of the Early Cretaceous plants in Northeast China. |
