Abstract: The Carboniferous strata are widely distributed in the Dulan County,Qinghai Province,northwestern China,belonging to the shallow water platform deposits with rich benthonic fossils,such as corals.brachiopods andfusulinids.The Present paper first reports some late Carboniferous conodonts from the Kruk Formation in the Shangxitai area,Dulan County,Qinghai Province,such as Stretognathodus expansus,Streptognathodus sp.,Idiognathodus cf.sinuosis,Idiognathodus sp.and Neognathodus sp.A.This discovery is clearly of great significance for the stratigraphic subdivision and correlation of the Carboniferous in the Dulan area of Qinghai.
