Corals have been growing in the oceans around the world for almost 500 million years.
The corals thrived in warm shallow marine waters and over time were buried in sediments as the land surface was juggled by crustal plate movements or the oceans rose and fell. Temperature and pressure from compaction during burial, resulted in those deposits, in time, becoming rock and part of the present day geological record.
Decorative coraline limestone and marble are popular building materials and have been used for centuries. For many years, ancient coral deposits have been mined for their high quality calcium, potassium, magnesium and sodium content which is used in health supplements. Fossil coral has also been used in fertilizers. Fossil coral has even been used in filters to remove impurities such as chlorine and formaldehyde from water.
