| Abstract: | ln this paper,trace fossils collected from the Sinian-Cambrian boundary beds in Western Sichuan and Eastern Yunnan area are studied. Where the boundary beds with abundant fossils are thick and have a clear sequence of organism evolution. The assemblages of trace fossils can be used for the delimitation at the bottom boundary of Cambrian system and help reconstruction of the palaeoenvironment. |
