Notice that they are all aligned in one direction as they were buried by a mudflow sweeping in from the continent. The arms, bodies and stems are all pretty much aligned. This seems to have occurred fairly regularly in this area at this time.
Also notice younger, smaller specimens have fewer plates and arms.
