摘要
辽西建昌县喇嘛洞镇肖台子地区出露一套沉积地层,富含介形类、脊椎动物及大量植物化石.经区域地层研究,结合1∶2000地质剖面实测以及对该剖面各层化石的采集,并对植物化石进行重点研究,确定了此套地层位于义县组之上,属于九佛堂组.生物化石组合面貌与"热河生物群"晚期群落特征一致,其时代为早白垩世.
A set of sedimentary strata, which is rich in fossils such as Ostracoda, vertebrate and numerous plants, outcrops in Xiaotaizi area of Jianchang County, western Liaoning Province. With study on the regional stratigraphy, combining with the survey of 1：2000 geological profile and collection of fossils, especially plant fossils, in each horizon, it is concluded that the set of strata is above Yixian Formation, belonging to Jiufotang Formation. Formed in Early Cretaceous, its features of biological fossil assemblage are consistent with those of the late community of Jehol Biota.
