This is an excellent example of a natural association of Pennsylvanian fossils. The quarry where this specimen was found has been filled with water and closed to collecting for many years. Many experts agree that this site produced the finest Pennsylvanian crinoids in the world.
There is a beautiful Brabeocrinus christinae crinoid preserved at the top of the plate. This crinoid has a very ornate cup and branching, uniserial arms with the individual plates arranged in a somewhat ''zig-zag'' pattern. A section of stem is still attached to the crinoid. Directly below the Brabeocrinus are two unidentified gastropod. These ''snails'' have great dark color and are easily seen on the plate. Below the gastropods, to the left, is a wonderful example of the rare crinoid, Clathrocrinus clinatus. This crinoid has long, branching arms, and this specimen has a long stem intact. Next to the Clathrocrinus is an excellent example of a solitary, or ''horn'', coral. This coral has very fine detail preserved. This plate has five specimens of four different species of organisms represented. It is easily one of the most prolific plates of different Pennsylvanian animals found at this locality.
