They have tentacles with nematocyst or stinging cells. The building unit of a bryozoan colony is usually termed a zooid. The building unit of a coral colony is usually termed a polyp. They are hermaphrodites. They can be both hermaphroditic and gonochoristic (unisexual). Bryozoans are complex and advanced corals with a mouth and anus.

This is the first evidence of intergrowths between Devonian rugose corals and bryozoans. In this case bryozoans provided a suitable substrate for the settlement of corals, which were subsequently encrusted by the bryozoans. The reconstruction is not drawn to scale. from publication: Danian cold-water corals from the Baunekule facies, Faxe Formation, Denmark: A rare taphonomic window of a coral mound flank habitat ...This is a 7.8" wide plate of coral and bryozoan cross sections, collected from Issoumour, Morocco.

Brachiopod Fossils. The most common seashells at the beach today are bivalves: clams, oysters, scallops, and mussels.

Over 12,000 fossil species of these hinge-valved organisms have been …Sep 17, 2009 · Bryozoans don’t quite produce anything quite so massive because they’re more tree-like and have a lot more spaces in them. They produce a structure that’s a little less, a little less organised than a coral reef and a little less dense, and so we have adopted the word ‘thicket’ to describe a bunch of bryozoan colonies all together. The microbial-sponge-bryozoan-coral bioherm of Kongul Yayla in the Central Taurides (South Turkey) contains a rich and diversified fauna. Sponges and rugose corals are of particular interest.…
