通过醋酸浸泡法，从贵州瓮安陡山沱组磷块岩合化石的残渣中挑选出磷酸盐化实体化石，鉴定为磷酸盐化原肠胚化石，与大量已报道过的后生动物休眠卵和胚胎早期发育阶段的卵裂球共生．化石形态为扁球形，大小与已报道的胚胎化石相似，中间发育一向内洼陷的孔状结构，呈现由囊胚内陷向原肠胚过渡的形态特征．这一发现使目前争议较大的陡山沱期动物胚胎化石得到进一步确认，为研究相关化石的亲缘关系提供了重要的化石资料．
Phosphorylated solid fossils were selected from residues of fossil assemblages of Phosphorite from Doushantuo Formation, Weng’an, Guizhou by acetic acid soaking method, and identified as phosphated gastrula fossils. Compared with a large number of dormant eggs and embryos of metazoa Early stage of blastomere symbiosis. The fossil has the shape of a flat sphere, similar in size to the previously reported embryo fossils, and has a hollow structure with an inward depression in the middle, showing the morphological characteristics of the transition from the blastocyst to the gastrula. This discovery further confirmed the currently controversial fossil embryos of the Doushantuo period and provided important fossil data for studying the genetic relationship of related fossils.
