      Common questions

      Fossils in rock layers are formed through a natural process that involves the gradual replacement of original organic material with minerals from the surrounding rock. This process, known as permineralization, can take thousands to millions of years to complete, depending on the conditions present. As a result, the fossils that are formed are remarkably well-preserved, providing a window into the past. The rock layers themselves are created through a combination of geological processes, including erosion, sedimentation, and plate tectonics.

    • Underground excavations: Areas where fossils can be found in mines, tunnels, and other underground excavations.
    • How are fossils created?
