摘　　要：本文报道产自贵州西南部中三叠世拉丁期晚期竹杆坡组的软骨鱼类鱼鳞化石,这些化石归属于4属6种,其中有3新种,即Rugosicoronaci rcacarina sp.nov.,Fragilicorona wanlantricuspis sp.nov.和Glabrisubcorona triridgecorona sp.nov.。并将中国西南部与加拿大东南部相当地层中软骨鱼类微体化石进行了初步对比。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 SW China and SE Canada are discussed briefly.
