· Limestone is a sedimentary rock. It’s made up of calcium carbonate. It forms from the shells and bone fragments of organisms, meaning it has lots of fossils. It’s a great building material and is used for flooring, walls, and decoration. Limestone often has fossils that give us a glimpse into the past.
