埃迪卡拉生物群(580~541Ma)是“寒武纪大爆发”前夕埃迪卡拉纪最为独特的宏体化石生物群,它在早期宏体生物的演化过程中占有极为重要的位置。该生物群自1947年在澳大利亚首次发现以来,已在全世界大约30个地区发现,但长期以来,在中国一直未发现典型的埃迪卡拉生物群。最近,古生物研究所陈哲、周传明研究员等在三峡地区灯影组的碳酸盐地层中发现了多种类型的埃迪卡拉生物群典型分子,总体面貌可以与纳米比亚、澳大利亚等世界其他地区的相比较。更为重要的是三峡地区 The Edicala biota (580-541 Ma) is the most distinctive macro-fossil biota on the eve of the “Cambrian explosion” and plays a very important role in the evolution of early macro-organisms. Since its first discovery in Australia in 1947, the biota has been found in about 30 regions of the world. However, a long time ago, no typical Eddie Kala biota has been found in China. Recently, researchers of the Paleontology Institute Chen Zhe and Zhou Chuanming discovered many typical types of Edicala biota in the carbonate formations of the Dengying Formation in the Three Gorges area. Their overall appearance can be compared with that of other parts of the world such as Namibia and Australia . More important is the Three Gorges area
