陕南早寒武世灯影组宽川铺段和埃迪卡拉系陡山沱组中产有磷酸盐化和硅化的球状化石, 其中的一些已被归入可能的后生动物胚胎化石，由于具完好的三维保存方式以及近乎完美的胚胎发育序列, 为早期后生动物的起源、分类、谱系演化以及发育生物学提供了不可多得的实证材料, 引起学术界的广泛重视。胚胎化石研究已成为近20年来发展起来的一门新兴学科。然而随着研究的深入, 多数寒武纪胚胎的生物学分类位置不定; 而数量异常巨大、又有独自的保存方式的晚元古代陡山沱组胚胎的真伪和生物学归属, 更是争议未消。现代胚胎的实验埋藏学研究可能会这些问题的解决带来一线曙光。本项研究试图通过对几类现生生物胚胎的实验埋藏学研究，讨论其在腐解、埋藏各阶段保存潜力；探讨胚胎在实验埋藏阶段形态、结构变化与陡山沱期及早寒武世胚胎化石的异同；磷酸盐化埋藏实验过程中胚胎的保存潜力及形态结构变化。

Some phosphatized and silicified spherical fossils from the Ediacaran Doushantuo Formation and Early Cambrian Kuanchuanpu Formation have been classified as possible metazoan embryo fossils. With their intact three-dimensional preservation, as well as near-perfect sequence of embryonic development, those fossils provide rare empirical evidence for the study of origination, classification, lineage evolutionary and developmental biology of early metazoa. The study of embryonic fossils has become one of the fastest developing discipline in the past 20 years. However, with further research, the biological classification of majority Cambrian embryo remain uncertain; whileas, the authenticity and biological attribution of the unusually preserved embryos in the Neoproterozoic Doushantuo Formation still in heated controversy. The taphonomic experiments on modern embryos may bring a ray of hope to those these problems. This study attempts to discuss their presevational potential in various stages such as decomposition and bury by taphonomic experiments on embryos of several extant organisms; to explore similarities and differences in morphology, structure and texture between embryos in experimental stage and those of the Doushantuo and Early Cambrian; The preservational potential and morphological changes in the phosphatized taphonomic experiment of embryos.
