在扬子地台寒武纪最早期 (梅树村期 )发现的磷酸盐化保存的后生动物Olivooides具发育的不同阶段 .从胚胎细胞分裂的囊胚期经可能的原肠胚期至胚胎的组织分化期最后直至幼体孵化 .后生动物胚胎化石的研究为古生物学研究开辟了一个新领域———化石胚胎学 .早期后生动物胚胎学研究对了解寒武纪大爆发中的生命的个体及系统发育有重要意义
Olivooides, a phosphated conserved metazoan found in the earliest Cambrian period (plum tree period) of the Yangtze Platform, developed from a different stage of development from the blastogen stage of embryonic cells through the possible gastrulation stage to embryonic tissue Differentiation period until the larvae finally hatch the metazoan embryonic fossil research for paleontological research has opened up a new field --- fossil embryology. Early metazoan embryology study to understand the Cambrian explosion in the life of the individual and phylogeny There’s important meaning
