A general overview of crinoid and bryozoan anatomy is also presented as a resource for students. GEOLOGIC SETTING. Late Ordovician world.Oct 6, 2011 · Figure. Anatomy of a basic bryozoan zooid, illustrated by a vertical section through a cheilostome zooid with the lophophore extended. The red arrows indicate feeding current flow. When not feeding the lophophore can be withdrawn through the orifice or aperture into the body walls. Zooids can take several forms, but the most common forms in each class are autozooids, which function in feeding the colony and excreting waste. Branching bryozoans may look similar to branching corals, but the zooids in bryozoa do not have septa or a columella as corallites do in corals. Figure 7.19 – Common bryozoan fossils.Unit II CH 7.

Among cyclostome bryozoans, the calcitic skeleton is usually lamellar, consisting of tabular or lath-like crystallites stacked like tiles at a low angle to the wall surface.
