摘要
Leaf fossils are collected for this study from the Shengxian Formation in Tiantai,Zhejiang Province.There are abundant compressed angiosperm fossils and a few gymnosperm fossils in the Shengxian Formation.Based on steady macromorphology of leaf including the base,the apex,the vein and so on,one species of Lauraceae plant fossils is studied in detail by analyzing the leaf architecture and cuticle characteristics in this paper.The fossil leaves and living Cinnamomum bejolghota(Buch-Ham.)Sweet are found sharing resemblance on the leaf shape,leaf vein,vein cell,stomata type and the features of trichomes.So the fossil leaves are identified as Cinnamomum bejolghota.Based on cuticle characteristics of fossil leaves and the distribution area and survival environment of living Cinnamomum bejolghota,we come to the following conclusions on the paleoclimate and paleoenviroment in eastern Zhejiang,that it was hotter and moister than present,and the distribution area of Cinnamomum bejolghota moved southward from Miocene.
