Elasenia is a genus of Ediacaran animals. The genus contains two species.
The genus was formerly included under Inordozoa, incertae sedis by Fedonkin. It was classified as a Coelenterate, but after the break up of the taxon into two different phylums - Cnidaria and Ctenophora - the current position of this animal is uncertain.Ivantsov, Andrei Yu.; Fedonkin, M.A. (2002). "Conulariid-like fossil from the Vendian of Russia: A metazoan clade across the Proterozoic / Palaeozoic boundary". Palaeontology. 45 (6): 1219–1229. doi:10.1111/1475-4983.00283. S2CID 128620276. It may be related to the extinct Trilobozoans (now considered a separate phylum) or the possible cnidarian class Cyclozoa.
