摘要
产于贵州瓮安、福泉、开阳地区晚新元古代陡山陀期磷块岩中的多细胞藻类 ,大型带刺疑源类 ,蓝菌丝状体和细菌化石、球状微体化石、后生动物化石等构成的瓮安生物群是世界上目前发现保存最完美的一个古生物群之一。本文在简单介绍瓮安生物群研究现状的基础上 ,首次批露了笔者近些年来觅获和初步研究的单细胞原生动物、多细胞类海绵动物和类腕足类后生动物等一批新的动物化石资料 ,为地球早期动物起源 ,早期生物组织分化 ,适应辐射、生物多样化和早期海洋生物生态系统提供了珍贵的化石实证材料。此外 。
A microfossil assemblage consisting of abundant multicellular algae,large spinose acritarchs, cyanobacteria and bacteria, large spheroidal microfossils and some epigenetic animal remains found from the phosphate rocks of the Doushantuo Stage of the Late Neoproterozoic at Weng'an-Fuquan and Kaiyang areas, Guizhou province was named Weng'an Biota and presently it well preserved very abundant older biota for earlier stage biosphere on the earth. The actualities of studies on Weng'an Biota are generalized by the writer, a set of new data of the animal remains available in present years, including unicellular protozoan, multi-cellular sponge animals and similar brachiopodous epigenetic animals, are firstly reported with the preliminary studies, they provide very rare demonstration of the fossils for origin of earlier stage animal, differentiation of earlier biology tissues, adaptation of radiation and biologic variety, and ecosystem of earlier marine biology. In addition, the significance treatment of Weng'an Biota is carried out.
