Abstract:
In this study,through continuous pure cultivation in laboratory,we obtained diverse forms of microbial colonies. The morphological comparison between fossils of Ediacara biota and modern microbial colonies reveals that (1) Aspidella shows similarities to disc-like microbial colonies in the body shape and the radial ridges on the surface; (2) the "rangeomorphs" shows similarity to microbial colonies with fractal-like branches structure in the branching structure; (3) Arkarua adami shows similarity to pentago...
