Here is an exceptional plate of Archimedes sp. from the Mississippian of Missouri. This unusual cork-screw shaped bryozoan is unique to the Mississippian of North America. There are EIGHT specimens of Archimedes on this plate. This is a natural occurrence - no specimens have been added or composited! It is extremely unusual to find this many specimens in such close proximity to each other. These bryozoans are very 3-dimensional and have been prepared in high relief. The white fossils contrast nicely with the grey matrix. The Archimedes are nicely positioned on the rounded rectangular plate of limestone. This is one of the best Archimedes plates we have ever seen.
