The second way it forms is through the process of evaporation -- again, as fresh water or salt water creatures die, their shells and bones are broken up and dispursed in water. When that water is in a shallow area such as a stream or cave, it will evaporate due to the environment around it and leave behind the calcium carbonate from the shells and bones.
