Also found, but not so commonly, are armored fish called placoderms, snails, sharks, stromatolites, trilobites and blastoids .This is why roughly 15,000 species of fossil bryozoans are known to science. Hidden origins Despite all these fossils, the origin of bryozoans has remained a mystery.Bryozoans (Ordovician to today with no peak period) are animals that live in a colony and excrete a skeleton to support themselves. Sometimes the skeleton is made of minerals, and sometimes it is made of chitin. Bryozoans are primarily marine, but are sometimes found in tidal or delta environments. Each animal in the colony is called a zooid.
