Limestone is formed in two ways. It can be formed with the help of living organisms and by evaporation. Ocean-dwelling organisms such as oysters, clams, mussels and coral use calcium carbonate (CaCO3) found in seawater to create their shells and bones. As these organisms die, their shells and bones are broken down by waves and settle on the ocean floor where they are compacted over millThis forms in the setting where the environment is watery and just like any other limestone, it also forms in warm and shallow marine waters where the environment is capable of supporting organisms that are able in generating the calcium carbonate and extracting the needed sources to form the calcium carbonate for their shells and skeletons.
