Reveal the biological properties of camamy "ancient ball eggs" fossils.

Recently, Yin Zongjun, an associate researcher at the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences, and others made progress in the study of "ancient ball eggs" in the difficult fossils in the Early Kagawa Pao biome in the Cambrian early Cambrian period.
ancient ball egg fossil is a phosphate microsphere spherical suspect species in the early Cambrian era, which appears in a large number of Kagawa paving groups at the bottom of the Cambrian system of the Yangzi plate in China.
's biological properties have been unknown since it was first reported in 1977.
although there have been scholars who have speculated that they may be eggs from early-lived animals, there is no reliable evidence to support them.
Yin Zongjun and others used the high-resolution microCT technology of Nanjing Paleontology to reconstruct for the first time the three-dimensional structure of the ancient ball eggs of the early Cambrian phosphate-phosphate difficult fossils, and found that the ancient ball eggs had solid tumor-like surface decoration, huge thick porous bags and cystic packets in different stages of cell groups.
internal cell groups follow the non-growth division pattern in the division process, i.e. the total product of the biological individual does not change significantly in the cell division process, and as the cell division progresses, the number of cells is increasing but the volume of individual cells is getting smaller and smaller.
these biological features are very consistent with the dormant eggs of modern aquatic invertebrates such as foot, rota, etc., suggesting that the ancient ball egg fossils are likely to be stagnant/dormant embryos of early Cambrian animals.
the discovery proves the biological properties of ancient ball egg fossils as dormant embryos in later animals, and provides new materials for the study of early development patterns of animals, and confirms the ancient origin of the dormant mechanism of animal embryos.
the late-stage breeding embryos of the Edicara-Ji-Mountain group disappeared at the end of the Edicara period, this particular developmental mechanism of the animals did not disappear and continues to this day.
modern aquatic animals through the development of dormant eggs to survive such as lack of oxygen in the water body and other adverse to reproduction of the environment.
ancient ball eggs in the early Cambrian era, the global wide spread also suggested that the ocean (light sea) water body oxidation level is far from normal levels.
the discovery also provides a revelation for re-evaluation of the biological properties of the widely distributed suspected fossils of the cambrian period.
