中科院南京地质古生物所的研究人员选取了以前容易被人们忽视的黑色硅质磷块岩,磨制岩石薄片进行镜下观察。此种传统的研究方法虽然得到的是二维平面保存的化石,但是却能保存更精美的细节。研究人员通过近千余片薄片观察,发现了数百枚保存了内部微细结构的动物胚胎状化石。这些化石内部不仅具有以前报道的内部细胞分裂特征,内部细胞从1个至2n个的球体都有发现,而且更重要的 Researchers at the Nanjing Institute of Geology and Palaeontology at the Chinese Academy of Sciences selected black siliceous phosphatic blocks that were previously neglected by people and polished thin slices of rock for microscopic observation. Although this traditional research method is a two-dimensional planar saved fossils, but can save more beautiful details. Researchers observed nearly a hundred sheets of flakes and found hundreds of embryonic fossils of animals with preserved internal fine structures. Not only do these fossils have previously reported internal cell division features, internal cells are found from 1 to 2n spheres, and more importantly
