Most modern sponges live in the ocean and usually have basket-shaped bodies. They live by filtering food and oxygen out of water pumped in through openings in their body walls and out through a larger opening at the top.Fossils are the traces or remains of organisms buried and preserved in sediments. They consist not only of hard body parts, such as bone and shell, but also may be impressions of plants, or tracks, trails, and burrows.

Bryozoans come in three growth forms: massive (a mound with no planned shape), branching (where the structure forms intricate branches), and fenestrate (where in life the bryozoan would have large, soft appendages coming out from the skeleton). Fossil RangeAt least 3,500 living species and 15,000 fossil species are known. Bryozoans are small animals (just large enough to be seen with the naked eye) that live exclusively in colonies.
