What is the formula for calcium carbonate?
Calcium carbonate is a chemical compound with the formula Ca CO 3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of eggshells, snail shells, seashells and pearls. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It has medical use as a calcium supplement or as an antacid, but excessive consumption can be hazardous and cause hypercalcemia and digestive issues; as well it was noted that "many calcium supplement formulations contain [the chemical element] Lead and thereby may pose an easily avoidable public health concern," especially in those supplements which were not derived from natural oyster shells.

How does calcium carbonate preserve fossils?
Most of the vertebrate fossils of the Two Medicine Formation —a geologic formation known for its duck-billed dinosaur eggs—are preserved by CaCO 3 permineralization. This type of preservation conserves high levels of detail, even down to the microscopic level. However, it also leaves specimens vulnerable to weathering when exposed to the surface.
What are some industrial sources of calcium?
Eggshells, snail shells and most seashells are predominantly calcium carbonate and can be used as industrial sources of that chemical. Oyster shells have enjoyed recent recognition as a source of dietary calcium, but are also a practical industrial source. Dark green vegetables such as broccoli and kale contain dietarily significant amounts of calcium carbonate, but they are not practical as an industrial source.
