J. Sprinkle 1973Early eocrinoids with strongly differentiated oral and aboral plated surfaces. Aboral portion made up of a large conical calyx and a smaller, long or short, cylindrical, attachment holdfast, both having numerous adorally imbricating plates. Oral surface covers large adoral end of conical calyx and consists of large or small adjacent plates bearing numerous epispires (sutural pores). Ambulacral system confined to oral surface, consisting of a central covered mouth, 5 radially arranged ambulacral grooves depressed into the oral surface, and numerous biserial brachioles alternately arranged alongside each ambulacrum. Anal pyramid located at edge of oral surface in "CD" interradius; possible hydropore-gonopore combination located between it and mouth. Two genera; early Cambrian
