The earliest fossils are the simple discs from the Twitya Formation in the Mackenzie Mountains; although they have not been found in other areas, this assemblage has been characterized as Ediacaran Assemblage I (Narbonne et al. 1994). Dating to about the same time are trace fossils which may have faecal strings. This is importance evidence, for it suggests that a complete gut (with an anus) was present in these bilaterians. Sponges are known to have evolved by this time. The remaining localities of Ediacaran fossils are dated to the last 20 million years of the late Neoproterozoic.
