The Wenghui biota, which is found in the Ediacaran Doushantuo Formation in Northeast Guizhou, is composed mainly of macroalgae (18 species of 15 genera, one unnamed macroalgae, and macroalgal holdfast forms described herein), and contains macroscopic metazoan, putative metazoan and trace fossils. This biota not only contains some elements of the Miaohe biota from West Hubei, the Lantian flora from South Anhui, the Ediacara fauna in Australia, and the White Sea biota in Russia, but also has its own characters to distinguish other Ediacaran biota.

产自于黔东北伊迪卡拉系陡山沱组的瓮会生物群生活环境应在贫氧的、透光性良好的浅海低能环境，以宏体藻类为主，共描述15属18种（其中包括3个新属、5个新种、2个修定属和4个修定种）和1个未命名藻以及不明藻类固着器，另包含有宏体后生动物，可能的后生动物以及遗迹化石。

The biomarkers such as the n-Alkanes, the isoprenoids, the terpane, and cholestane were detected through GC-MS analysis. Based on the study of the biomarkers, the biological evolution during Permian and Triassic can be divided as three stages, namely, the mixing source stage of low biota such as thallose and advanced plant in late Permian (below bed 63), the stage of low biota such as thallose in the boundary transitional layer (bed 63-69) and the mixing source stage of advanced plant and low biota such as thallose in early Triassic (above bed 69). What's more, the second stage near the boundary transitional layer can be subdivided into 4 stages. The stages of biota evolution is close related with sedimentary environment changing and the boundary transitional layer.

利用GC—MS分析技术，在陆相地层中检测出正构烷烃、类异戊二烯烷烃、萜烷和甾烷类生物标志化合物并根据生物标志化合物和特征值研究，将二叠系—三叠系生物演化划分为三个大的阶段，即晚二叠世的菌藻类低等生物与高等植物混源阶段（63层以下），界线异常层的菌藻类低等生物阶段（63-69层）和早三叠世高等植物与菌藻类低等生物混源阶段（69层以上），界线附近异常层的第二阶段又进一步细分为4个次一级阶段，生物演化阶段与沉积环境变化及界线异常层具有非常密切关系。

Due to the relatively unique macrofossil assemblages in the Sinian strata of South China, its comparison with the Ediacara-type Biota occurring abundantly abroad in the strata postdating the last glacilation of Neopro-terozoic (including the Avalon Biota, the Pound/White Sea Biota and the Nama Biota) remains to be studied in detail in future.

由于华南震旦纪宏体化石具有较为独特的组合面貌，与国外末次冰期后大量出现的伊迪卡拉型生物群(阿瓦隆生物群，庞德/白海生物群和纳马生物群)如何对比，还有待深入的研究。
