Chalk - CaCO3

Wood ash - mainly CaCO3/CaO

Calcite - CaCO3

Mollusc shells - polymorphic forms of CaCO3

Limestone/aragonite/dolomite - crystalized/sedimented CaCO3

Reindeer antlers - Almost all of the calcium carbonate in the body is being stored in the bones.

Calcium carbonate (CaCO3) is the second most abundant mineral in the earth's crust and occurs in many different three-dimensional forms. Limestone for instance is a rock composed mostly out of calcite and aragonite (different crystal forms of CaCO3). CaCO3 is often a component which stands for protection and rigidity in mollusc shells and bones of sea creatures. After the shells settle on the bottom of the ocean for millions of years, they form limestones. Calcium carbonate in all of the used materials, is constantly transforming into different shapes and through different mediums.
