The most common remains are fragments of the mesh that are detached from the central structure, and these may not ... Bryozoans are chiefly identified using skeletal characteristics such as spines and other surface structures as well as the form of the pores and the shape and size of the colonies (Smith 1995, 231). Archaeological specimens may be damaged, making identification to species level difficult.Coralline Crag bryozoans divide into two main types. The first group consists of those that form sheet-like or, more rarely, branching encrustations on the surfaces of shells or other bryozoans. The second comprises erect species, a variable assemblage of colonies that grew in three dimensions from a fixed base.Bryozoans feed on small particulate material and would probably do well in some aquaria, particularly those with a good sand bed which produces a lot of bacterial particulates. They may also feed on the smaller varieties of phytoplankton such as small Nannochloropsis species. The most ancient bryozoans are from the Lower Ordovician.

They seem to be closer to Trochozoa than to Ecdysozoa or Deuterostomia in most molecular analyses. Alas, the bryozoan genome is as derived as its morphology, making it a difficult subject for molecular methods.Bryozoans (commonly called moss animals) are generally sessile, colonial invertebrates that belong to the phylum Bryozoa (or Ectoprocta), which is sometimes combined with two other phyla (Phoronida and Brachiopoda) to form a possible clade within the Deuterostomia. The three are sometimes referred to as the Lophophorata.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.Colonies of Bryozoans are started by a single individual, which after its larval existence settles onto a substrate and after a little growth begins to reproduce asexually (by budding). Thus a bryozoan colony is composed entirely of clones (genetically identical individuals) of the first animal – which is called the ancestrula.Mississippian limestones in Illinois are generally pure carbonate with little shale or sand and often have caves systems in them.
