Actinocrinitidae calyx - internal cast, this is the central head of a sea lily. The top cup, or "tegmen" is faceted, and the arms which attach in pairs around the periphery would have been attached to the ends of the forked tubes coming up from the bottom basal cup. Where my thumb is touching is the attachment for the long stem.
