A piece of agate turned out to be a dinosaur egg.

An unusual agate from the British Museum turned out to be a dinosaur egg. British scientists have found that an unusual spherical piece of agate from India, kept in the Natural History Museum in London since the 1880s, is actually a dinosaur egg almost 60 million years old. The discovery was made using computed tomography. Scientists suggest that the egg fell into the area of ​​the volcanic eruption and was covered with lava. After that, for hundreds of years, silicates were gradually washed out of the eggshell and agate was formed.
