Taxonomy from Fossilworks.org. Description from Südkamp 2017, p. 132: " Medusaster is a small ophiuroid with generally 11 to 15 arms. They are slender, taper in the distal part and end in blunt extremities. The disc has the same size as the mouth frame, which included the robust mouth-angle plates together with the large triangular second ambulacrals. The ambulacrals are fused into half vertebrae which are mostly aligned with their opposites. The laterals are sickle-shaped and bear some slender spines." Identified by oilshale.
