The Inner Secrets of Rocks and Fossils

Researchers at UCLA have produced the first 3D images of fossils embedded in rocks aged between 650 and 850 million years old.

The research allows them to spot signs of ancient microscopic life, such as fossil cell walls and could be useful in studying extraterrestrial rocks in the search for alien life.
