Quick Summary

The Cystoporata are an order of bryozoans, which are small, colonial aquatic invertebrates. This order was introduced in 1964 and includes fossil groups like the ceramoporoids and fistuliporoids. These bryozoans existed from the Ordovician to the Permian periods. Their skeletons were long and tubular, connected by pores, and contained transverse partitions. Unique supporting structures called cystopores were also present between the zooid skeletons. The ceramoporoids, part of the Cystoporata, are thought to be the ancestors of the fistuliporoids, which were successful until the end of the Permian period.123
