| Abstract: | This paper reports14genera and26species of conodonts in Carboniferous strata at Lubanshi ,Lixian.Of these,12genera and22species are for the first time reported,including Declinognathodus lat-eralis,D.noduliferus noduliferus,Gnathodus bilineatus costiformis,G.bilineatus bilineatus,Gondolella gymna,G.xinjiangensis,Neognathodus bassleri,Neoprioniodus barbatus,Idiognathodus claviformis,I.del-icatus,I.klapperi,Idiognathoides sinuatus,I.sulcatus,Lochriea commutata,Ligonodina typa,Lonchodina tarimensis,L.bischoffi,Lonchodus simplex,Streptognathodus expansus,S.parvus,S.suberectus,Ozarko-dina hindei.Among them,the genera Streptognathodus,Declinognathodus,Neognathodus,Idiognathodus and Idiognathoides are representative elements in the lower part of the Upper Carboniferous and the genera Streptognathodus gracilis and Gondolella are representative elements in the upper part of the Upper Car-boniferous. |
