摘要：通过对白垩纪掌鳞科针叶树Pseudofrenelopsis gansuensis Deng，Yang et Lu丰富的营养枝和表皮分析，提供了新的资料。该物质是在吉林省汪清县罗子沟盆地下白垩统地层的一个新地点发现的。在距汪清约150 km的延吉盆地大喇子组中，Pseudofrenelopsis是一种常见的植物，但存在不同的种，只有Pseudofrenelopsis dalatzensis。甘肃酒泉早白垩世已有P.dalatzensis和P.gansuensis的记录，但它们所处的地层不同。罗子沟下白垩统含植物地层过去常与延吉盆地大喇子组进行对比。甘肃云杉在酒泉的层位比达拉特云杉低，可能表明它们在吉林的层位也不同。掌鳞科针叶树是我国早白垩世红层中为数不多的化石。甘肃拟无齿蛇葡萄的发现，为华北边远地区两个独立盆地早白垩世陆相红色矿床的划分、对比和地质时代的确定提供了重要依据。
Abstract: New data from abundant vegetative shoots and cuticular analysis are provided for the Cretaceous cheirolepidiaceous conifer Pseudofrenelopsis gansuensis Deng, Yang et Lu. The material was found from a new locality of the Lower Cretaceous strata in the Luozigou Basin, Wangqing, Jilin Province, northeastern China. Pseudofrenelopsis is a common plant in the Dalazi Formation of the Yanji Basin about 150 km from Wangqing, but there exists different species, Pseudofrenelopsis dalatzensis only. Both P. dalatzensis and P. gansuensis have been recorded from the Lower Cretaceous of Jiuquan, Gansu Province, but they are in different stratigraphic horizons. The Lower Cretaceous plant‐bearing strata in Luozigou have used to correlate with the Dalazi Formation of the Yanji Basin. The discovery of P. gansuensis, which is lower in horizon than P. dalatzensis in Jiuquan, may indicate that they are also different in horizon in Jilin. Cheirolepidiaceous conifers are among the few fossils of red beds of the Early Cretaceous in China. The present discovery of Pseudofrenelopsis gansuensis provides important evidence for classification, correlation and determination of geological ages of the Early Cretaceous non‐marine red deposits of the two separate basins in remote areas of North China.
