Limestones consisting mainly of animal shells. The shells of many animals, those that live either in the sea or in freshwater, consist of calcium carbonate (calcite and aragonite). When the animals die, their shells are left on the ocean floor, lake bottom or river bed where they may accumulate into thick deposits.
