The word “fossil,” comes from the Latin word “fossilis,” which means “dug up.” Fossils often are found in limestone and they represent a variety of extinct marine invertebrate animal life forms, including brachiopods, bryozoans, clams, corals, crinoids, nautiloids and snails. Most living gastropod shells (and most other mollusks with shells) are composed of the mineral aragonite. Aragonite is a carbonate mineral that is stable at the earth's surface, but dissolves and is replaced by other minerals during burial and fossilization. In some cases, the minerals in buried snail shells are replaced.Most fossils form when a dead organism is buried in sediment. Layers of sediment slowly build up. The sediment is buried and turns into sedimentary rock. The remains inside the rock also turn to rock. The remains are replaced by minerals. The remains literally turn to stone. This type of fossilization is called permineralization.The protoconch of a fossil cone snail from the Dominican Republic viewed using a scanning electron microscope (SEM).
