Bryozoan fossils often look like small, branching twigs. It is fairly rare to find an entire bryozoan colony completely intact, but it is very common to find smaller, broken pieces. In Ohio, bryozoans are most commonly found in the fossil-rich Ordovician rocks of southwestern Ohio.Bryozoan. Bryozoans (from the ancient Greek for “moss animals”) are so named because some living bryozoan colonies resemble mosses. Not to be confused with plants, bryozoans are invertebrate animals with a long fossil record, from the Early Ordovician Period to the present. Modern species inhabit freshwater, brackish, and marine environments. Bryozoans: Phyla Entoprocta and Ectoprocta. Bryozoans are generally sessile (attached to substrata) colonial invertebrates that use ciliated tentacles to capture suspended food particles. This group is primarily marine, with more than 4,000 species worldwide, about 50 of which are freshwater species ( Pennak, 1978 ). Crinoids are marine animals belonging to the phylum Echinodermata and the class Crinoidea. They are an ancient fossil group that first appeared in the seas of the mid Cambrian, about 300 million years before dinosaurs. They flourished in the Palaeozoic and Mesozoic eras and some survive to the present day.Despite their small size, marine bryozoans are abundant in many fossil assemblages thanks to the preservability of their hard calcium carbonate skeletons.

Many bryozoans have similar outward appearance, which can make them difficult to identify to genus or species. This month’s fossil, however, is the easy-to-identify bryozoan, Constellaria. 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. Fossils can tell us what life was like on Earth in ancient geologic time, helping geologists describe ancient depositional environments and …Fossils are the traces or remains of organisms buried and preserved in sediments.

Bryozoans are common in today’s oceans, where they are frequently found encrusting rocks or shells. During the Paleozoic era, however, bryozoans commonly grew off of the sea floor as erect structures.

Collecting Fossil Bryozoans Bryozoans can be found as fossils in a wide variety of marine rocks. They are so abundant that their piled-up branches make the frame work for some limestones, Bryozoans, like brachiopods, contain a tentacle-bearing lophophore used in feeding and gas exchange. They also contain a U-shaped gut with a distinct mouth and anus. Bryozoans are inconspicuous fossils, but can be seen most easily on slabs of Ordovician limestone or dolomite with the aid of a magnifying glass or hand lens. Bryozoa. Bryozoans, also known as the Polyzoa, Ectoprocta or moss animals, are a phylum of small aquatic animals living in colonies. The colonies usually have a skeleton of calcium carbonate. Bryozoans have a long fossil history, starting in the Ordovician. In their life-style they resemble the polyps which form coral.Bryozoan colonies are protected with a covering of organic materials or calcium carbonate. Some calcium carbonate forms may be found as fossils in the ...Bivalves (also called pelecypods) are clam and clam-like, shelled invertebrate (lacking a backbone) animals. Bivalves are a class of mollusk with two valves, which is where they get their name (“bi” means two in Latin).

As all pioneer species, bryozoans are resilient organisms that are small, simple, and capable of colonising in a hostile environment, altering and creating less stressful conditions for a more complex successional species as in facilitative successions (Bruno et al., 2003). These screw-shaped fossils were support structures for Mississippian fan-shaped bryozoan colonies, called Archimedes. Note the small Taxocrinus crinoid body fossil in the lower left corner.

The colonies of different species take different forms, building exoskeletons (outer protective structures) …Bryozoans, or "moss animals," are aquatic organisms, living for the most part in colonies of interconnected individuals. A few to many millions of these individuals may form one colony. Some bryozoans encrust rocky surfaces, shells, or algae. Others, like the fossil bryozoans shown here, form lacy or fan-like colonies that in some regions may ...The major ranks are domain, kingdom, phylum, class, order, family, genus, and species.
