摘　　要：The aim of this study is to discuss the microfossils in phosphate deposit in the Doushantuo stage, Sinian System, weng’an, Guizhou Province. Based on the detailed observation in morphology and microstructures, it is considered that those acritarchs with interior spicules probably belong to sponge animals. However, some explanations for a part of soft-tissue are stili contrioversial. The reliable conciusion stili needs more evidence to study. The scientific significance of this study and the key questions for further studies are suggested here.The aim of this study is to discuss the microfossils in phosphate deposit in the Doushantuo stage, Sinian System, Weng’an, Guizhou Province. Based on the detailed observation in morphology and microstructures, it is considered that those acritarchs with interior spicules probably belong to sponge animals. However, some explanations for a part of soft-tissue are still controversial. The reliable conclusion still needs more evidence to study. The scientific significance of this study and the key questions for further studies are suggested here.
