We are proud to present this specimen for the bryozoan connoisseur. This is a large Archemedes 'screw'' from the Mississippian of Missouri. This unusual, corkscrew-shaped bryozoan is unique to the Mississippian of North America! Once in a great while, an Archimedes is found that retains the fronds that emanate from each spiral. And, once in a great while, that specimen can be prepared to display those fronds - this is one of those specimens. The corkscrew-shaped axis is quite evident, and the individual fronds are very pronounced and exhibit fine detail. The individual holes in the net-like fronds are easily seen. The fossil has good color and contrast and is well positioned on the somewhat rectangular plate of matrix. This is a museum quality specimen of this unique bryozoan.
