  ABSTRACT: In the middle Cretaceous vegetation changed rapidly for the diversification of angiosperms, there are few extensive analyses of the plant fossils (including leaves, fruits, seeds and woods) from this period in China. New abundant fossil plants collected from the upper Lower Cretaceous Dalazi Formation in the Luozigou Basin, Wangqing, Jilin Province were studied and 25 species belonging to 17 genera were recognized. Up to date totally 39 species belonging to 25 genera were discovered in the Luozigou Basin. The assemblage is composed mainly of conifers (47.5%) and early angiosperms (30%) and indicates that the vegetation was a transitional flora between the Early Cretaceous fern-gymnosperm flora and the Late Cretaceous angiosperm flora. The flora was a Pseudofrenelopsis-angiosperm assemblage in succession of Early Cretaceous flora and the late Early Cretaceous, probable Albian in age. During the late Early Cretaceous, the Luozigou Basin was dominated by hot and arid climate and sometimes probably interrupted by wet climate.
