摘要
The Chuaria circularis fossils from the Kaili Biota are black-brown carbonaceous films, circular to oval, outline clear, periphery smooth, no concentric ring, shield surface smooth, that is similar to the characteristics of the Chuaria circularis fossils from the Meso-Proterozoic. Chuaria circularis survived the extinction event of the terminal Ediacaran, however the characteristic of the thallus morphology exhibits minimal change, that probably indicates Chuaria circularis is a phytoplankton with a wide ecological tolerance and flexibility and its conserved morphology may reflect a greater fitness for competition and a high degree of inherent genetic stability. The occurrence of Chuaria circularis from the Kaili Biota has some significance to the evolution research of the early macroalgae.
