The Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences (CAS) has announced the discovery of a series of embryo fossils dating back 610 million years ago in Long’an, southwest China’s Guizhou Province.

Caveasphaera is found in the form of a ball with a diameter less than one mm, and is fully preserved as a multicellular structure.

“More than 100 pieces of stone tools and embryo fossils were discovered in a larger cave”

The researchers used three-dimensional imaging technology to reconstruct the structure of hundreds of fossil samples. The results showed that its evolutionary process is similar to the evolutionary process of unicellular relatives of animals but is also more complex.

Fossils discovered record a key stage in the development of animals from monocytes to multiple cells, and the stage lays the biological basis for the emergence of animals with distinctive cells and tissues in real.
