In writing the most recent research article, Aviculopinna, I set up an area to photograph specimens. While having this setup available, I went ahead and re-photographed the first seven specimens in the fossil catalog. Specimen CG-0001 John Harper identified this specimen as possibly being Orthotetes, a brachiopod. The preservation isRead More →

These layers are all exposed as part of the Glenshaw formation, the dominant formation within Parks Township. The examples below represent a few of the many different cephalopods genera that are available. Found Cephalopod GenusRead More →
