Calcareous nannofossils ( see FOSSIL PLANTS | Calcareous Algae) as a group are composed of several forms, such as coccoliths, nannoconids, and discoasters.

The fossil record shows that nearly all the crinoid species died out at this time. The one or two surviving lineages eventually gave rise to the crinoids populating the oceans today. Based on the fossil record of crinoids, especially the details of the plates that made up the arms and calyx, experts have identified hundreds of different crinoid ... These bryozoans have a geologic range from the Ordovician period and can still be found in present day. Cyclostomates have a ciccular aperture and tubular walls. A profound way to identify this type of bryozoan is the relation to the “ Aulopora” coral.

Ancient fossil material discovered in the hills of China revealed the previously unseen “soft parts” of Protomelission gateshousei, formerly believed to be the earliest Bryozoan.

The animal must exert muscle power to open the shells, and when their muscles are relaxed the shells close. As a result, fossil brachiopods are frequently found with both sides together.

They resemble clams, but are a distinct type of marine animal. Bryozoans live together in colonies and form branching stemlike, lacy, or encrusting forms. A single zooid is hardly bigger than a comma on a printed page. Features of the skeleton are of great importance in taxonomy, which means that it is usually possible to identify species using dried specimens.
