Bryozoan coral

Mar 9, 2023 · Marine bryozoan colonies tend to grow on or attach to solid substrates such as shells, rocks, large brown algae, mangrove roots, ship bottoms, and the undersides of icebergs. They live at all water depths and all latitudes. Growth forms of bryozoans are sometimes encrusted and coral-like and create miniature “reefs” in shallow water habitats.

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, The coral unit is the polyp while the bryozoan unit is the zooid. Both have tentacles used to capture prey and their bodies are permanently fixed to the colony mass, i.e. sessile. Both coral polyps and bryozoan zooids are able to extend from and contract within the colony matrix.Cold-water coral ecosystems are involved in the formation of large seabed structures such as reefs and giant carbonate mounds, and they represent unexploited paleo-environmental archives of earth history. Like their tropical cousins, cold-water coral ecosystems harbour rich species diversity. Despite the great water depths, commercial interests ...

The fossil fauna is highlighted by abundant and diverse crinoids and brachiopods, plus corals, bryozoans, including Archimedes (corkscrew bryozoan), molluscs, sharks, and fish, but trilobites are rare. Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) [6] are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about 0.5 millimetres ( 1⁄64 in) long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding.The high energetic environment representing accumulation of debris from bryozoan-coral-pelmatozoan thickets contains 8 species dominated by erect branched species (6 species).Late Ordovician.
