Conodonts, ranges from Cambrian to Triassic, were distributed widely in the palaeocean. The species variety, morphotype, big or small, and output rate of Triassic conodonts are controlled by the factors of the sea water such as salinity, depth, temperature, and hydrodynamic condition. Different ecological characteristics of conodonts, i.e. conodont faces indicates different sedimentary environment. Therefore, according to the conodont facies and abundance of the characteristic conodont species, the sedimentary facies regions (platform facies region, platform-margin facies region, basinal facies region) can be recognized, and Triassic palaeogeographic face can be reconstructed, but also the conodont biogeographic regions can be recognized. Early Triassic conodonts in China are belonged to the Asia biogeographic province, Tethys biogeographic realm, and can be subdivided into two biogeographic subprovinces and several communities.
