Ammonoids grazed in and on the meadows of less mobile animals. Among the fishes sharks were especially common while bony fishes included coelacanths, acanthodians, and lungfishes. The common open communications between the …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.
