埃迪卡拉纪微化石记录具有多样性，包括丝状蓝藻、多细胞藻类和疑源类，在北方宜昌樟村坪埃迪卡拉纪陡山沱组发现一个新的微化石组合，其中包括丝状蓝藻（拟颤藻属、多囊藻属、Salome属、管藻属）、多细胞藻类（Sarcinophycus，Wengania）和疑源类（赤藓属，Ericiaspaera，Knollisphaeridium，Leiosphaeridia，（Meghystricophaeridium和Tianzhushania）在本区硅质结核中首次发现了疑刺类，其新微体化石组合与东峡地区陡山沱组二段的微化石组合相似贵州瓮安上部磷块岩。
The Ediacaran is characterized by diversification of many groups in microfossils record,including filamentous cyanobacteria,multicellular algae and acritarchs.A new microfossils assemblage from the Ediacaran Doushantuo Formation at Zhangcunping,northern Yichang,China,includes filamentous cyanobacteria (Oscillatoriopsis,Polytrichoides,Salome,Siphonophycus),multicellular algae (Sarcinophycus,Wengania) and acritarchs (Appendisphaera,Ericiasphaera,Knollisphaeridium,Leiosphaeridia,Meghystrichosphaeridium and Tianzhushania).Acritrachs are found at the first time in the chert nodules in this region.The new microfossil assemblage is similar to that from the member Ⅱ of the Doushantuo Formation in the East Yangtze Gorges area and the upper phosphorites in Weng'an,central Guizhou.
