| Abstract: | The Lower Member of Meitan Formation contains abundant fossils in Wudang,Guiyang,Of which graptolthines and brachiopods are common.Brachiopods are totally 10 genera and 10 species,attributed to 4 orders,5 superfamilies and 6 families,which indicates a higher diversity.Brachiopod Sinorthis is the dominant genus,therefore the brachiopod assemblage belongs to the Sinorthis fauna.The study of brachiopods in the Lower Member of Meitan Formation provides new information for the Early Ordovician evolution and radiation of brachiopda,and even for the total Ordovician. |
