Fossil coral types.
Fossil organisms may provide information about the climate and environment of the site where they were deposited and preserved (e.g., certain species of coral require warm, shallow water, or certain forms of deciduous angiosperms can only grow in colder climatic conditions). Fossils are useful in the exploration for minerals and mineral fuels.
