Eoandromeda is an Ediacaran organism consisting of eight radial spiral arms, and known from two taphonomic modes: the standard Ediacara type preservation in Australia, and as carbonaceous compressions from the Doushantuo formation of China,
where it is abundant.Affinity
The organism was first interpreted as a trace fossil, and has also been considered to represent an agglutinating foraminiferan.  However, the discovery of the Chinese fossils, which have preserved organic matter, ruled out these interpretations, because the Burgess shale type preservation displayed required relatively robust organic material to start with.  Its spiral form has also led to comparison with the fossil embryos also preserved in the Doushantuo formation; the exact purpose still remains out on this until intermediate forms are found.The organism bears a very superficial resemblance to echinoderms, ctenophores and to some of the other Ediacara biota, but it lacks sufficient physical characteristics to ascertain with any degree of certainty whether it is indeed an animal or not.  If it is, it would be the earliest known fossil of an adult animal; and its anatomy is consistent with that expected from the earliest animals.  However, it is not perfectly clear that it is an animal; algae, the dominant constituent of the Doushantuo biota, cannot be ruled out, except that Eoandromeda seems a little too complex.
