Description: Presented is an uncommon Calymene breviceps from the Waldron Shale. The specimen is fully prone, 3D, and very well preserved. It is just about maximum size for the species. It came from the classic St. Paul Stone Quarry. The quarry has now been closed to collecting for some time, so specimens of this quality are now at a premium. Complimenting the aesthetics of this piece is the beautifully detailed unidentified partial crinoid stem and the smaller partially disarticulated Calymene.
