Prehistroic Models: Mollusca
After Arthropoda (bugs), Mollusca is the second largest phylum (classification) of invertebrate animals. They include clams, snails, squid, chitons and limpets. Most have Calcium carbonate shells, which are abundant in the fossil record and are often used as index fossils.
