Opalized crab claw: How do opalized fossils form?

Opalized fossils are extraordinary treasures that form when the conditions are right for opal formation. The burial of bones, shells, or pinecones in sand or clay can lead to the opalization process, where silica replaces the original organic material, creating a stunning fossil replica. These opalized fossils showcase the captivating beauty of opal and provide a window into the ancient world.
