Upper Ordovician, 452 Million Years old. 

Cystoporida, also known as Cystoporata or cystoporates, are an extinct order of Paleozoic bryozoans in the class Stenolaemata. Their fossils are found from Ordovician the 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.

Some of the families of Cystoporida bryozoans include 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 (Ordovician-Devonian), and Xenotrypidae (Ordovician-Silurian).

Cystoporida bryozoans are found in various parts of the world, including the western Altai-Sayan Folded Area, where eight bryozoan species of the order Cystoporida were described from the Emsian Stage of the Lower Devonian.
