Conodont is the predominant fossil which is used to study the Ordovician stratigraphy. Although the conodont biozones which can be correlated in the globe have been built up, the correlation of each continent has not been paid more attention to, especially there is not conodont biostratigraphy constraint by high precision and accurate chronological data. We compiled the published Ordovician conodont biostratigraphy data of Asia and preliminarily set up an Ordovician conodont stratigraphy framework. Furthermore, in combination with the progress of International Geologic Time Scale, we proposed the solution for the Ordovician conodont biostratigraphy studies which should be addressed; that is, based on the running program IGCP 652 and the task of the China workgroup, we should carry out multiple stratigraphy studies for the Ordovician strata in southwest Ordos, and set up the improved conodont biostratigraphy.
