They are distinctive among animals for their high taxonomic, ecological, and environmental diversity. The reasons for this evident "evolutionary success," however, remain unclear.The oldest known corals lived during the Cambrian, more than 500 million years ago, and are still found living today. Some, like octocorals (which have has eight ‘arms’) are soft bodied and rarely preserved as fossils, but others secrete a hard, calcarous (made of calcium carbinate) skeleton and are thus important rock-forming organisms.In many gastropods, a platelike cover, the operculum, is attached to the foot and closes the shell opening when the head and foot are retracted within the shell. The shells of fossil gastropods vary enormously. Some are coiled in one plane (similar to the shells of coiled ammonoids); others are coiled so that they produce spires of varying heights.Gastropods.
