Bryozoans are small animals (just large enough to be seen with the naked eye) that live exclusively in colonies. In fact, the Phylum Bryozoa is the only animal phylum in which all known species form colonies. The name comes from two Greek words, bryon (moss) and zoon (animal ...Fossils are often said to take a million years to form. However, as of 2014 it has been proven that a fossil can take a shorter period of time to form. This period can be a thousand years or less.Echinoderm - Evolution, Adaptations, Paleontology: Phylum Echinodermata was already well diversified by the Lower Cambrian Period; the extensive fossil record has many gaps. There is much disagreement about the classification of echinoderms. The subphyla are Homalozoa (carpoids), Blastozoa (blastozoans), Crinozoa (sea lilies and feather stars), Asterozoa (sea stars), and Echinozoa (sea cucumbers).

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. See below for some of the most common fossils found in Missouri.

Clams and their relatives (oysters, scallops, and mussels) are often called bivalves (or bivalved mollusks) because their shell is composed of two parts called valves. Bivalves have a long history. Their fossils first appear in rocks that date to the middle of the Cambrian Period, about 510 million years ago.Facts on Fossils - Vertebrates.
