Cystoporida

Cystoporida, also known as Cystoporata or cystoporates, are an extinct order of Paleozoic bryozoans in the class Stenolaemata.[1] Their fossils are found from Ordovician to Triassic strata.[2]

Scientific classification Edit this classification
Domain: Eukaryota
Kingdom: Animalia
Phylum: Bryozoa
Class: Stenolaemata

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.[3][4]
