carbon is an element, so "carbon" can't exist of anything. But the carbon found in fossil fuels are mostly from shells and dead animals or plants, after being exposed to imense heat and presure by stacking layers of sediment, plants and shells
limestone. A rock made up mainly of the shells or fragments of shells of megascopic (clams, oysters, snails) animals is a coquina. If the rock is composed of the shells (tests) of microscopic plants and animals it may be called chalk. Limestone can be a hardened chemical precipitate of CaCO3 without an organic source, and take many forms: oolite for example.
In general no. However, living things can incorporate minerals in their structures such as the shells of sea creatures and the bones of animals or structures in plants. Sometimes after the animal dies these minerals are left behind in the shapes that the animals or plants made them.
