Fossilized Coral Ring
When prehistoric corals are fossilized through replacement with agate, the fossil coral forms through hardened deposits left by silica-rich waters. Which creates the fossilized coral here. The entire process can take over 20 million years and occurs only under very unique geological conditions. Corals are marine animals and it is their skeletons that are fossilized and preserved, often leaving flower-like patterns in the stone.
