贵州寒武系地层中赋存有丰富的早期后生生物群，它们不仅包括丰富的动物化石，还产出大量的宏观藻类化石。这些宏观藻类组合经历了一个从埃迪卡拉纪后期极度繁盛到末期渐渐衰败再至寒武纪早期逐渐复苏直至寒武纪中期再度繁盛的过程。期间，宏观藻类组合特征及藻体形态特征都发生了很大变化，且有一些属种穿越新元古代-寒武纪界限。这些现象的发生与该时期海洋环境变化情况及生态系统生物类群相互关系有着密切联系。本项目以贵州寒武系早期后生生物群中的分枝型宏观藻类为研究对象，借助微体化石处理方法及电镜扫描和能谱分析等手段，将各生物群分枝型宏观藻类系统分类完善，并在此基础上进行宏观藻类在古生态、古沉积环境等方面的初步研究，最终目的是探索埃迪卡拉纪-寒武纪宏观藻类的演化趋势。从而为整个早期后生植物（宏观藻类）及低等植物登陆前的漫长演化提供材料。

The important Ediacaran to Cambrian early metazoan biotas in Guizhou Province contain not only rich animal fossils, but also a diverse macroalgal flora. The latter provides a key opportunity for research on the composition and evolution of early metaphytes, thereby making a significant contribution to the understanding of the evolution of the entire plantae. Preliminary work suggests that the evolution of macroalgae from the late Ediacaran to Early Cambrian Epoch 3 had experienced a “flourishing – descending – lowering – ascending –flourishing” process. There are many changes of the algal assemblages and algal morphology in this process, but there appear to be some genera that cross the boundary between the Neoproterozoic and Cambrian. All of this must have to do with the changes of the marine environment and the correlations between the various biological groups in the ecological system. To document the evolution of macroalgae across this interval in detail, it is necessary to perfect taxonomic study of this material. To do so, methods such as microfossil processing, scanning electron microscopy (SEM), and DES will be used. This study will also examine the palaeoecology and the palaeosedimentary environment of these units in Guizhou.
