Cystomeson
''Cystomeson'' is an extinct genus of cystoporate bryozoan of the family Fistuliporidae Fistuliporidae is an extinct family of bryozoans within the order Cystoporida. Members of this family have lived from the early Ordovician to the late Triassic The Triassic ( ) is a geologic period and system which spans 50.6 million years f ..., discovered in the U.S. state of New Mexico. It contains only one species, ''Cystomeson sierraensis''. It lived during the Mississippian period. Its colonies had a branching shape and possessed a vesicular skeleton, a layer of calcitic mineral material on the surface of the colony that contained acanthopores. Instead of being hollow as in the similar genus Cheilotrypa, its colonies were solid, and its autozooecia derived from distinctive axial zooecia.

Cystoporata
Cystoporata, also known as Cystoporida or cystoporates, are an extinct order of Paleozoic bryozoans in the class Stenolaemata. Their fossils are found from Ordovician to Triassic strata. All cystoporatan bryozoan genera (around 50 or so) have a "cystopore", a chamber-like supporting structure, separated from each other by transverse septa, situated between the characteristically elongated zooecia of each individual colony. Families * Acanthoceramoporellidae (Ordovician) * Actinotrypidae (Carboniferous-Permian) * Anolotichiidae (Ordovician) * Botrylloporidae (Ordovician-Devonian) * Ceramoporidae (Ordovician-Devonian) * Constellariidae (Ordovician-Silurian) * Cystodictyonidae (Devonian-Permian) * Etherellidae (Permian) * Evactinoporidae (Carboniferous-Permian) * Fistuliporidae (Ordovician-Permian) * Goniocladiidae (Devonian-Permian) * Hexagonellidae (Ordovician-Permian) * Revalotrypidae (Ordovician) * Rhinoporidae Rhinoporidae is an extinct family of bryozoans wit ...

Bryozoa
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Most marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the marine bryozoans (Stenolaemata), freshwater bryozoans (Phylactolaemata), and mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. At least two genera are solitary (''Aethozooides'' and ''Monobryozoon''); the rest are colonial. The terms Polyzoa and Bryozoa were introduced in 1830 and 1831, respectively. Soon after it was named, another group of animals was discovered whose filtering mechanism looked similar, so it was included in Bryozoa until 1869, when the two groups were no ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...
