Just west of the town of Dego, in the Savona hinterland, you can see several remains of what about 26 million years ago was a limited but prosperous coral reef rich in corals, algae, molluscs, sea urchins and many microorganisms that populated the seabed.

In the University magazine, at the useful link, Prof. Briguglio, UniGe professor of paleontology and paleoecology, tells the story of the Dego reef and its importance in the study of climate change.
