Found an embryo of an unknown animal that lived 500 million years ago

The find in Hubei province in southern China came as a complete surprise to researchers Jess Brosa and James Schiffbauer, experts in prehistoric animals. Imagine their surprise and delight when they found tiny petrified spheres with polygonal patterns on the surface in the limestone layers.

After a thorough examination on high-precision equipment, the scientists came to the conclusion that they were holding fossilized embryos of an unknown living creature. In total, about 140 embryos were found, which, most likely, were then in the stage of reproduction. Their shell consisted of phosphates with a calcite core located inside and turned into stone over millions of years.

Archaeologists have found fossilized embryos of prehistoric animals before, but this Chinese find is unlike any of them. Scientists are confident that new discoveries lie ahead.
