Identify the TRUE statement about fossil preservation.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.

Bryozoans are tiny animals, no larger than 4 millimeters (5/32 of an inch) wide. They float alone for a time, but eventually form colonies, working together for mutual benefit. In this way, they are much like coral.Bryozoan thickets can provide substrate or habitat for many other organisms, including hydroids, ascidians, barnacles, worms, sponges, sea stars, crustaceans, ...The Bryozoa are the only animal phylum with an extensive fossil record that does not appear in Cambrian or late Precambrian rocks. The oldest known fossil bryozoans, including representatives of both major marine groups, the Stenolaemata (tubula r bryozoans) and Gymnolaemata (boxlike bryozoans), appear in the Early Ordovician . It is plausible ...Mineralized bryozoan skeletons first appeared in rocks making them the last major phylum (large group of related animals or plants) to appear in a fossil record. This has led researchers to suspect bryozoans arose earlier, but were initially unmineralized, and may have differed significantly from fossilized and modern forms.

The upper Visean Derbyshire mud mounds are, thus, representatives of a newly defined fenestellid bryozoan–brachiopod–siliceous sponge mud mound category, occurring in various middle–upper Visean Western European sites, a sub-type of the fenestellid bryozoan–crinoid–brachiopod Type 3 buildups of Bridges et al.

The colonies are encrusting, erect or arborescent.Bryozoa. Bryozoa, also known as Ectoprocta, is a major invertebrate phylum, whose members, the bryozoans, are tiny, aquatic, and mostly sessile and colonial animals. Also known as moss animals or sea mats, the colonial species of bryozoans generally build collective stony skeletons of calcium carbonate that are superficially similar to coral .A particular, and regionally very restricted, mechanism of in situ beach sand production is the precipitation of carbonate around small seeding particles, which are constantly being moved around by wave action in shallow waters (Simone, 1980).The resulting particles are known as ooids or oöids (Siewers, 2003).They are mostly 0.2–1.0 mm in diameter and …Orange-rust colored biofouling on propeller is a colony-forming organism called a bryozoan (Watersipora subtorquata) Biofouling reduction is primarily achieved through the use of antifouling coatings, applied in dry dock at regular intervals, which work either through chemical or mechanical means to discourage attachment or accumulation of fouling.Bryozoans are microscopic aquatic invertebrates that live in colonies.

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

Encrusting bryozoans form flat sheets that spread out over rocks, shells, and other substrates. Forms that grow upwards into the water column may be massive (solid), foliaceous (sheetlike, with zooids on both sides), dendroid (branchlike or treelike), or fenestrate (many branches joining and rejoining to form a netlike or "windowed" shape). , Bryozoans are a classic "wild card" taxa, jumping around in otherwise stable phylogenies.
