Abstract：The evolution of Rodinia surpercontinent has always been of concem as an important scientific issue.Paleobiogeographic region analysis,as an effective method to solve the problem of the tectonic reconstruction of the continental masses,has rarely been applied to Rodinia.Longfengshan biota,characterized by Chuaria-Tawuia-Longfengshania,is one of the typical biota,whose biotic factor can be found globally,in the nearshore shallow water basin and Lagoon,Tonian.According to the reliable existing biota data reported globally,we make the paleobiogeographic analysis,zoning them into North China Craton-North Laurentia region(ChuariaTawuia-Longfengshania) and Yangtze Crator-India Craton region (Chuaria-Tawuia),constitute a low-latitude-Macroalgae realm (1 000-780 Ma).Furthermore,we have a new cognition on the position of North China Craton,in the east of Rodinia surpercontinent,near Laurentia Craton,and Yangtze Craton in the west,close to India Craton.
