Limestone and it history

Limestone The formation of limestone Lime stone is a sedimentary rock made of dead animal shells formed deep down in the ocean; limestone also contains a large amount of calcium carbonate. Carboniferous limestone is a different type of limestone. It was formed around 350,000,000 years ago as a marine deposit in a warm, clear, shallow sea.
