bryozoans have this kind of feeding current, and it apparently was the way that the Paleozoic fenestrates (Figure 6) handled the water from which they fed. 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,

record), the most obvious difference is size: bryozoan zooecia are tiny, while coral calices are often much larger. Bryozoan zooecia are sometimes covered by a mineralized “roof” with a small hole or operculum serving as an access hatch to the surrounding seawater, while the corallites of colonial corals are “open-topped”, with septa,Azooxanthellate corals, bryozoan mounds, coral mounds, NW Euro-pean shelf, Cretaceous, Paleocene, coral distribution Introduction Schlager (2000) differentiated three carbonate factories comprising the mound, the tropical, and the cool-water carbonate factories.

We can ...The dwelling tubes of corals are also filled with radial dividing ridges called septa - the bryozoan tube has no filling and appears as a simple hole. The biology of the coral animal is simpler in that it does not have a pass through digestive system - food is taken into the mouth and waste products later expelled from the mouth.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.
