| 摘 要： | 本文根据中国三叠纪牙形石的地理分布、属种的分异度和特征属种的丰度，将中国三叠纪牙形石归属Kozur(1973)的特提斯生物大区亚洲生物省，在早-中三叠世，进一步二分为喜马拉雅生物亚省和华夏特提斯生物亚省，后者三分为西华夏特提斯生态区、东华夏特提斯生态区和右江生态区。在晚三叠世时，右江生态区已不复存在。

| Abstract: | On the basis of the geographic distribution,the diversity of the genera and species,and the plenty of the characteristic genera and species,the Triassic conodonts in China are attributed to the Kozur's Asian Province of Tethyan Main Province.Furthermore,this province can be divided into two subprovinces of Himalayan Biogeographic Subprovince and Cathay Tethyan Biogeographic Subprovince in the Early Middle Triassic,and Cathay Tethyan Biogeographic Subprovince can be subdivided into three biomes of Eastern Cathay Tethyan Biome,Western Cathay Tethyan Biome and Youjiang Biome.The Youjiang Biome disappeared during the Late Triassic. |
