Limestone is a sedimentary rock made primarily from calcium carbonate, usually in the form of calcite and aragonite. Its grains vary in size and can consist of a variety of materials including shells, coral, and mud. It is typically off-white to gray in color and usually forms in shallow marine environments.Desert sandstones usually lack fossils. River-channel and deltaic sandstones may contain fossil wood, plant fragments, fossil footprints, or vertebrate remains. Beach and shallow marine sands contain mollusks, arthropods, crinoids, and other marine creatures, though marine sandstones are much less fossiliferous than marine limestones.
