| 摘 要： | 本文描述了产于我国陕西西乡寒武系底部磷矿层中的藻类化石,在标本中发现多种藻枝保存类型和可能的"固着器"等特征;由于藻体微小、藻管中空等特征而将其归入蓝菌类寒武松藻属;可为早寒武世早期的藻类繁盛提供了新的小生境和新的食物来源、加速了后生动物的进化。

| Abstract: | The paper describes the fossils of Cambricodiumcollected from the basal Cambrian phosphoric strata of the Kuanchanpu Member of Xixiang County,Shaanxi Province,China.There are some preservation features of"dichotomic branche"and"holdfast"in Cambricodiumfossils.Due to the characteristics such as small size and hollow tube we classify these fossils into Cyanobacteria,CambricodiumJiang,1982.The Cyanobacteria bloom provides a new niche with new food sources and thus possibly accelerates the evolution of metazoan in early Cambrian. |
