They have a rich fossil record due to the presence of a calcareous skeleton in the great majority of species. Compared with the approximately 808 genera of extant bryozoans, an estimated 1289 genera are extinct …However, bryozoans are not closely related to marine corals. These gelatinous masses feed and reproduce together and range in size depending on the stage of the developing bryophyte.

Bryozoans rarely appear as principal frame builders, either alone or in conjunction with other organisms; an exception is a fossil reef from Vermont, USA, of Ordovician age (Pitcher 1964). These reefs are constructed by densely packed colonies of trepostomid bryozoans in upright growth position (Cuffey 1977).All bryozoans are colonial except one genus, Monobryozon. Thus, bryozoans typically form sessile colonies that live in marine and freshwater environments, and consist of individual zooids that are about 0.5 mm (0.02 in.) long.
