Bryozoan fossil identification. Bryozoans are microscopic aquatic invertebrates that live in colonies. The colonies of different species take different forms, building exoskeletons (outer protective structures) similar to those of corals. Most colonies are attached to a structure such as a rock or submerged branch. Freshwater bryozoans' exoskeletons are gelatinous (like jelly) or chitinous (like the "shells" of insects ...

Bryozoans, sometimes referred to as "moss animals," are a type of simple colonial animal that mostly lives in marine environments (a few inhabit freshwater).

At 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. Sponges (Phylum Porifera) are the simplest major group of animals; their earliest fossils appear in the late Precambrian. 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. ballard designs fabric by the yard Thus, bryozoans may have evolved well before their first appearance in the fossil record at the early Cambrian. Our divergence time estimate for the origin of bryozoans is younger than that of the time-calibrated phylogeny of Metazoa by Erwin [ 64 ] where the bryozoan lineage stretches back into the early part of the Ediacaran (approx. 630.0 Ma).The lack of body fossils of unmineralized bryozoan fossils in the Cambrian fossil record seems surprising given the increasing number of Lagerstätten available. It is worth noting, however, that soft-bodied bryozoans are also conspicuously absent from the Lagerstätten within the known stratigraphical range of the phylum.Because of their varied and easily identifiable forms, Paleozoic bryozoans are extensively used as index fossils. Bryozoans are significant because they are the only major phyla to appear in the Ordovician rather than the Cambrian. Figure 7.8 | Examples of Phylum Bryozoa. Question a a.
