Abstract:Some intercontinental period "standard fossils" were discovered in strata of Devonian and Carboniferous of South China, such as the important member Lepidodendropsis hirmeri of Early Carboniferous of North America and Europe, Carboniferous species of the genera Calamostachys Schimer, Palaeostachya Weiss etc.. They co-existing with Leptophloeum rhombicum, Cyclostigma kiltorkense, Drepanophycus spinaeformis, D. spinousus, Archaeosigillaria vanuxemi and Pseudobornia ursina, were living in Tizikou Formation of the Late Devonian. The standard fossils of western Europe and North America Westphalian, as Neuropteris gigantea, Sphenopteris obtusiloba, Potoniea Zeiller, Mariopteris acura f. obtusa, M. acuta, Linopteris Presl and Archaeopteridium Kidston, Cardiopteridium spetsbergense, Triphyllopteris collombiana, and Adiantites gothanii were discovered also in upper part of Ceshui Formation of Guangdong or middle part of Zhongxin Formation, lower and middle part of Zishan Formation in Jiangxi, Yejiatang Formation in wester Zhejiang and Lindi Formation in Fujian. Upper strata of Ceshui Formation in Guangdong and upper part of Zishan Formation contain Fusulinids and Brachiopods in Jiangxi. Therefore the authors consider that this Lepidodendropsis hirmeri, Calamostachys, Palaeostachya, Neuropteris gigantea, Sphenopteris obtusiloba, Potoniea, Mariopteris acura f. obtusa, M. acuta, Linopteris were originated in Later Devonian and Early Carboniferous Wisean Stage of South China. The article also discusses the origin and migration of plants during that era.
