Gastropods have left behind an extraordinary fossil record that documents a rich evolutionary history. They are distinctive among animals for their high taxonomic, ecological, and environmental diversity. The reasons for this evident "evolutionary success," however, remain unclear.Ammonites are not the only shell fossils. Brachiopods are non-coiled shell fossils and can be black, white, brown or gray. Sea urchins that have been preserved as a fossil are called echinoids and gastropods are fossils of snails.
