	Stenolaemata - Wikipedia, the free encyclopedia
		Stenolaemata are marine bryozoans with tubular zooids with strongly calcified walls.
		They are characterized by a lophophore which is protruded by the action of annular muscles.
		Stenolaemata were the predominant Bryozoan group during the Paleozoic.

	Bryozoa - Wikipedia, the free encyclopedia
		Almost always the first of the three is meant.
		Bryozoans can be further divided into 2 main classes: the Stenolaemata and the Gymnolaemata.
		Bryozoans are most likely to be found in marine environment, typically growing on surfaces of things, such as rocks, kelps, shells, fossils, and even on pipes and ships.

		There is no fossil record for this order because they do not emit a skeleton and uncertain ancestry.
		Stenolaemata are marine bryozoans have extended cylindrical zooids that continue to lengthen throughout their life.
		Stenolaemata is classified into follwing orders, cyclostomata, cystoprata, trepostomata and crytostomata.

	Notes on Bryozoans (Site not responding. Last check: 2007-10-26)
		In many cases, morphological trends that persist over the course of the Phanerozoic are due to the rise and fall (often to extinction) of major groups (or clades).
		Paleozoic bryozoans were Stenolaemata, whereas Cenozoic forms are Gymnolaemata - the different architecture of these groups will dominate any change from Ordovician to present.

	Fossil Record of the Bryozoa (Site not responding. Last check: 2007-10-26)
		The Bryozoa are the only animal phylum with an extensive fossil record that does not appear in Cambrian or late Precambrian rocks.
		The oldest known fossil bryozoans, including representatives of both major marine groups, the Stenolaemata (tubula r bryozoans) and Gymnolaemata (boxlike bryozoans), appear in the Early Ordovician.
		It is plausible that the Bryozoa existed in the Cambrian but were soft-bodied or not preserved for some other reason; perhaps they evolved from a phoronid -like ancestor at about this time.

	Chapter 9: Phylum Bryozoa
		The marine species are grouped into the classes Stenolaemata and Gymnolaemata.
		Because bryozoan classification into classes centers primarily on soft-anatomy, only selected orders will be discussed.
		The following four orders are assigned to Class Stenolaemata.

	Lophophorates
		Other types of zooids include kenozoids (polymorphs lacking internal organs, used as skeletal space fillers), maternal zooids (polymorphs with specialized brooding pouches), and avicularia (polymorphs with processes on the opercula which serve cleaning and other purposes).
		There are two major classes of bryozoans with fossil records, the Stenolaemata (Ordovician to Recent) and Gymnolaemata (Ordovician to Recent).
		This class of bryozoan was dominant during the Paleozoic.

		Most bryozoa found in rocks from the Ordovician to the Middle Cretaceous belong to this class.
		Stenolaemata are characterized by tubular or conical zooids.

		The phylum Bryozoa is divided into three classes, Phylactolaemata, Stenolaemata, and Gymnolaemata.
		These bryozoans live only in fresh water and have horseshoe shaped apertures.
