We describe an almost complete cup of the flexible crinoid genus Edriocrinus found in the Acanthopyge Limestone (Eifelian) in the Koněprusy region. The articulated cup, composed of an anal X and well defined radial plates, is preserved inside the living chamber of an orthocone cephalopod. This cup represents the stratigraphically youngest occurrence of the crinoid Edriocrinus in Bohemia.
