Topic: Gymnolaemata


In the News (Sun 3 Jun 12)

  
 [No title]
Ectoprocta is divided into subclasses Gymnolaemata and Phylactolaemata.
A second family of Gymnolaemata is described from New Zealand.
Identification to Bryozoa can be based on the mat-like or moss-like colonial growth pattern in conjunction with the structure of the zooids.

 Fossil Record of the Bryozoa   (Site not responding. Last check: 2007-10-23)
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.

 Notes on Bryozoans   (Site not responding. Last check: 2007-10-23)
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.
