Ordovician Bryozoan Fossils

The bryozoa, or "moss-animals" are actually colonies of living tubes. These living tubes are called zooecia. These tubes give the surface of bryozoa a porous appearance on close inspection. The diameters of the zooecia are typically the diameter of a pin or less. At first glance, the description sounds like that of coral, but brozoan zooecia are much smaller than the corallites found in coral and the structural differences are noticeable. Proper identification usually requires careful thin-sections.
