Bryozoan colonies appear in twig-shaped branching forms, fans, mounds, encrusting sheets, and others. As with corals, the shape of a bryozoan colony is influenced by the environment.

However, some of the supposed records belong to other coral families that show some features in common, such as Geyerophyllidae and Aulophyllidae. After a detailed revision of the bibliographic ...Bryozoans are zoologically unrelated to reef corals, of course, but their hard, calcareous crustose, mounded, and branching colonies superficially resemble those of cnidarians. Whereas in the tropics, bryozoans are mostly dwarfed by stony corals, in cooler temperate waters they come into their own, and can form bio-herms and mini-reefs.

This is the first detailed study of coral-bryozoan symbiosis from the Silurian; all previous reports describe Late Ordovician, Devonian, or Cenozoic material. The lack of malformations and decrease in the size of bryozoan zooids near the rugosans suggest there were no strong negative effects of the rugosans on the bryozoan.Fossils of many types of water-dwelling animals from the Devonian period are found in deposits in the U.S. state of Michigan. Among the more commonly occurring specimens are bryozoans, corals, crinoids, and brachiopods.
