This paper deals with the Elasmobranch scales discovered from the Zhuganpo Formation (Middle Triassic) in the southwestern Guizhou Province.4 scale genera and 6 scale species are described and illustrated,with 3 new species,such as Rugosicorona circacarina sp.nov.,Fragilicorona wanlantricuspis sp.nov.and Glabrisubcorona triridgecorona sp.nov.Their stratigraphic distribution and relationship with equivalent elasmobranch scales reported from Southwest China and Southeast Canada are discussed briefly.
