中文摘要：

通过对常见微生物种类进行纯培养获得多种微生物菌落形态，并将其与埃迪卡拉生物群化石形态进行对比研究，发现：1）盘状化石Aspidella与圆盘形菌落的轮廓和放射状分布的小脊具有相似性；2）“rangeomorphs”分支状化石与具有次级分支结构的菌落具有某些相似性；3）五边形似棘皮动物化石Arkaruaadami与五边形菌落较为相似；4）两侧对称类化石Kimberella与圆盘形边缘具放射状脊的菌落的表面形态非常相似；5）盘状化石Az—bumaresbrunsae与圆盘形表面具辐射状脊的菌落的轮廓和表面纹饰分布极为相似。以上对比结果表明部分埃迪卡拉生物群化石与微生物菌落形态具有一定的相似性。本研究为埃迪卡拉生物群化石生物属性的解译提供了新思路。

英文摘要：

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 similarities to dise-iike that （1） Aspidella shows microbial colonies in the body shape and the radial ridges on the surfaee; （2） the ＂rangeomorphs＂ shows similarity to micro- bial colonies with fractal-like branches structure in the branching structure; （3） Arkarua adarni shows similarity to pentagonal microbial colonies in the pentagonal body shape; （4） Kimberella shows similarity to disc-like microbial colonies with radial ridges at the edge in the disk-like body shape and the surface pattern; （5） Albumares brunsae shows similarity to microbial colonies with radial ridges on the surface. These results of comparative studies imply that microbial colonies can develop many shapes similar to some fossils of the Ediacaran biota. Therefore, this study provides a new possibili- ty to interpret affinities of numerous fossils from the Ediacara biota.
