Scientifically, you know, limestone is important because it contains many fossils, and those fossils can be used to date the rock so that the geological period of time in which the limestone’s formed can be determined. The same fossils can tell us a lot about the environment in which the limestone formed.Limestone has long fascinated earth scientists because of its rich fossil content. Much knowledge of the Earth's chronology and development has been derived from the study of fossils embedded in limestone and other carbonate rocks. Limestone also has considerable commercial importance.
