As with so many fossils from the Ediacaran, it is not certain to which phylum they belong. According to Fossilworks, Cyclomedusa belongs to Cnidaria. From Wikipedia: "Cyclomedusa was originally thought to be a jellyfish but some specimens seem to be distorted to accommodate adjacent specimens on the substrate, apparently indicating a benthic (bottom-dwelling) creature. The markings do not match the musculature pattern of modern jellyfish. The fossils have been conjectured to represent a holdfast for some stalked form — possibly an octacorallian, or something else entirely."
