摘　　要：From the stratotype section of the Bazhukeng Formation, Dengshan Group (formerly assigned to the late Proterozoic), situated at Dengshan Village, Zhujia, Yiyang County, Jiangxi Province, three dinoflagellate-bearing horizons have been found, in which the lower two contain ?Conochitina sp. and Cyathochitina sp., while the upper yields ?Conochitina sp.From the stratotype section of the Bazhukeng Formation, Dengshan Group (formerly assigned to the late Proterozoic), situated at Dengshan Village, Zhujia, Yiyang County, Jiangxi Province, three dinoflagellate-bearing horizons have been found, in which the lower two contain ?Conochitina sp. andCyathochitina sp., while the upper yields ?Conochitina sp. and ?Rhabdochitina sp., which testifies that the stratigraphic units concerned belong to the early Paleozoic in age. Such a discovery is significant for re-ascertaining the age of the “Banxi Group” in South China, and the tectontc namework and its evolution.
