Scyphocrinus, is an extinct genus of crinoids. Species belonging to this genus lived during the Silurian and Devonian periods (from 443.4 to 358.9 Ma).  Scyphocrinites had a lobolith, which is a floating sphere that keeps an animal afloat in water. Unlike other crinoids, Scyphocrinites hung upside down at the surface.
