Centimeter-scale macroscopic tubular fossil was discovered for the first time in silicalite of Sinian Liuchapo Formation in Xinhua County, Hunan Province. Its clear structure and body size can be compared with Gaojiashan biota in Ningqiang County of Shaanxi Province and Liaotuo tubular fossils of Hubei Province. The tubular fossils may be a new biological species and the most reliable metazoa in this area. In this paper the significance of the discovery in the study of early biological evolution has been discussed in combination with Ediacaran biota and biota in its upper and lower horizons.
