主 题:macroscopic organism paleo-community evolution biota and environment Ediacaran South China
摘 要:Macroscopic organisms lived in the Yangtze Sea of South China during the Late Doushantuo period of the *** results of the specimen collections and statistics within each meter show that the macroscopic biota from the Ediacaran Doushantuo Formation in northeast Guizhou,South China,can be subdivided into Globusphyton,Cucullus,Sectoralga-Longifuniculum, Beltanelliformis,and Baculiphyca-Gesinella *** paleo-community evolution indicates the relationship not only between biota and environment,but also between metaphytes and *** the Globusphyton paleo-community,through to the Sectoralga-Longifuniculum paleo-community,to the Cucullus paleo-community,the increase in the abundance and diversity of metaphytes(especially the branching macroalgae)and metazoans implies that the oxygen content in the seawater increased *** the Beltanelliformis and Baculiphyca-Gesinella paleo-communities could be related to a deteriorated environment and fragile *** emergence,abundance,and diversity of macroscopic metaphytes,which were closely connected with the environmental microchanges,accelerated the process,improving the environment and increasing oxygen,and established an important platform for the development of macroscopic metazoans.
