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).[1] [2]
The crinoid genus Camarocrinus have been considered by some authors the bulbous distal end of the stem of Scyphocrinus, having the function of a root and fixing the crinoid to the sea button.[3]
