What is bryozoa.

Carbonization is a type of fossil preservation in which the organism is preserved as a residual, thin film of carbon instead of the original organic matter. Leaves, fish, and graptolites are commonly preserved in this way. Compression of the original organism results in thin layers of carbon.Abstract. Lophotrochozoa is a protostome clade that includes disparate animals such as molluscs, annelids, bryozoans, and flatworms, giving it the distinction of including the most body plans of any of the three major clades of Bilateria.

Most bryozoans are marine creatures, but one class lives in freshwater. These are small, sessile, colonial invertebrates that have calcium-based skeletons (like corals).

Scientists have found bryozoans at depths of up to 8,200 metres but the majority live in much shallower waters.
