Scyphocrinites was a cosmopolitan crinoid with examples found of similar ages in the United States, Africa, Europe, and Asia. It has an intricate calyx with many stellate plates. A bulbous structure called Camarocrinus has been associated with these crinoids, and is the reason for its widespread existence in the Upper Silurian/Lower Devonian. This structure is believed to be a float, with the crinoid leading a pelagic existence, allowing it to cover much territory. They are sometimes found in mass associations.
