NONCALCAREOUS ALGAE OF KAILI FAUNA IN TAIJIANG, GUIZHOU

The Middle Cambrian noncalcareous algse are common fossils in the Burgess Shale of British Columbia. So fsr, the discovery areas of these fossils are confined to North America. Here described are some noncalcareous algae from the middle and upper parts of the Kaili Formation (Middle Cambrian) at Gedong, Taijiang, southeastern Guizhou. These algae are reported in China for the first time,and therefore the discovery not only has filled the gaps in the study of these algae in China and further increased the biotic content of the Kaili Fauna, but also has expanded the geographic distribution of the Bursess Shale algae, and provided some new materials for the study of paleogeography and paleoplate and comparison of early sarge plants between the eastern and western shores of the Pacific Ocean.,Among the algse described here, Mar~ sac and ~thai shachns are more abundant in theKaili Shale than in the Burgess Shale. Alga gen. et sp. indet. A and Alga gen. et sp. indet. B could be endemic tuxa in Taijiang I they have not been named for the time being because they are too few in number.
