Chalk (upper left) is a marine limestone consisting of tests of microscopic algae and foraminifera. Tufa (upper right) is a chemical precipitate of calcium carbonate. Fossils are very common in marine calcitic sedimentary rocks. Rocks such as coquina are wholly composed of fossils but so-called normal limestones may be also highly fossiliferous.
