Dickinsonia is a genus of extinct organism, most likely an animal, that lived during the late Ediacaran period in what is now Australia, China, Russia, and Ukraine. It is one of the best known members of the Ediacaran biota. The individual Dickinsonia typically resembles a bilaterally symmetrical ribbed oval. Its affinities are presently unknown; its mode of growth has been considered consistent with a stem-group bilaterian affinity,[3] though various other affinities have been proposed.[4][5][6] It lived during the late Ediacaran (final part of Precambrian).[7] The discovery of cholesterol molecules in fossils of Dickinsonia lends support to the idea that Dickinsonia was an animal,[8] though these results have been questioned.[9]
