Abstract: Preparation and study of a crinoid specimen in the Orton Museum collection reveal for the first time the tegmen roof of Plaxocrinus mooresi (Whitfield). The roof is flat and composed of 14 small polygonal plates encircled by 10 large spines which project laterally and abut along their sides proximally. The tegmen roof comprises part of the crown of a young individual showing the dorsal cup, plates of the posterior interradius, and adjacent arms. A portion of the tegmen roof of a mature crinoid is also referred to Plaxocrinus mooresi. Both specimens were collected near the base of the Allegheny Group, of Pennsylvanian age, at Carbon Hill, Hocking County, Ohio.
