【Abstract】 The abundant flora buried in the Fuxin Basin, western liaoning is a important one to study the geological ages of Mesozic Basins in China. The paper devotes mainly to describe and discuss the Ginkgophytes of Fuxin Formation Five genera thirteen species (including three unnamed species) in all are treated.Based on the Ginkgophytes mentioned with other specimens of fossil plants, their significance in Stratigraphy, Palaeobotany and Palaeogeography is elucidated. It follows that Fuxin Formation is assigned or, at least par-fially to the lower Cretaceous, The Fuxin Flora belongs to the Siberian province of the early cretaceous the Ginkgophytes(Particularly Ginkgo and Gin-kgoites) should not be classified so minutely that they are indistinguishable and should not be named so variously that they are insignificant in taxo-nomy.更多还原
