The lophophore can most easily be described as a ring of tentacles, but it is often horseshoe-shaped or coiled. Phoronids have their lophophores in plain view, as shown above, but brachiopods like the one below must be opened wide in order to get a good view of their lophophore. Brachiopods, articulated brachiopods in particular, represent the quintessential example of the power of extinction to effect macroevolutionary change (Stanley 1979).

Brachiopods are marine animals belonging to their own phylum of the animal kingdom, Brachiopoda. Although relatively rare, modern brachiopods occupy a variety of seabed habitats ranging from the tropics to the cold waters of the Arctic and, especially, the Antarctic.Clathrodictyids are the most abundant stromatoporoids in the Upper Ordovician Xiazhen Formation (middle to upper Katian) of South China. A total of nine species belonging to four clathrodictyid genera are identified in the formation, including Clathrodictyon idense Webby and Banks, 1976, Clathrodictyon cf.
