Prone Calymene Trilobite Fossils

Here are pictures of some Calymene breviceps trilobite fossils. They were found in the Waldron Shale of Indiana. They existed in the Silurian Period (about 425-419 million years ago). They have not been cleaned yet. Thanks to Kenny for letting me photograph them. The prone ones are about 4-5 cm long and 2-3 cm wide.
