    Taxonomy from Fossilworks.org.

    Description from Südkamp 2017, p. 147:" The small holothurian has a cylindrical form consisting of a distinct oral region with surrounding tentacles, and at the other end an elongate body that is rounded distally. The lobate arrangement of the 25 plated tentacles, the large ovate madreporite plate (perforated plate for entering of water), and the weakly developed calcareous ring are primitive features among the holothurians. The ossicles of the body wall are numerous small granules underlain by small plate-like elements. In the basal part thorn-like elements are more abundant."

    Identified by oilshale using Südkamp 2017.
