These are fossils that were mined from an individual layer that featured Calymene clavicula and Fragiscutum glebalis trilobites in association. They are from the Upper Silurian Henryhouse formation of Oklahoma within Pontotoc County from a locality known as Yellow Bluff along the east side of Bois D'Arc Creek. I will try to add some more photos to this section also of the trilobites and associated fauna from within the bed however this is a good representation.
