During the 1700s limestone was used for lithography which is when pictures are drawn on stones and then copied to other stones. Because limestone contains the remains of dead organisms it is considered an organic sedimentary rock. There are rare chemical sedimentary rocks that form from the precipitation of calcium carbonate from ocean water.
