| 摘 要： | 首次在湘西新化震旦系留茶坡组厚层块状硅质岩中发现个体大小达厘米级的管状宏体化石,内部结构清晰,从其个体大小、结构特征分析,并与相同层位的陕西宁强高家山生物群、峡东地区灯影组管状化石对比,认为是目前这一地区发现的最可靠的后生动物化石,可能系一新的种属。文中同时结合埃迪卡拉生物群及其上下层位生物群研究现状,简要探讨了其在生命早期演化研究中的意义。

| Abstract: | 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. |
