AI overview

Limestone is a sedimentary rock made mostly of calcium carbonate minerals that forms when calcium precipitates out of water, often through the accumulation of sea creatures like corals and shells. It's the main source of lime and frequently contains fossils that help scientists understand Earth's past.
