2.5" Plate of Archimedes Screw Bryozoan Fossils - Alabama

Here is a small plate of Archimedes sp. from the Bangor Formation of Alabama. This unusual cork-screw shaped bryozoan commonly referred to as an "Archimedes Screw" is unique to the Mississippian aged rocks of North America. There are a variety of other bryozoa fragments and crinoid stems peppered throughout the limestone. This plate comes with an acrylic display stand.

Bryozoans are microscopic aquatic invertebrates that live in colonies, forming skeletal structures similar to corals. Each skeletal structure has a form unique to each particular species. The individual byrozoans forming these colonies are fileter feeders called zooids, straining nutrients from the surrounding water.
