Ediacaran Fauna - Taxonomy  

The taxonomy of the Ediacaran Fauna is likely to remain in flux for some time. A number of fossil specimens have been given 2 or more names. There is also disagreement about which taxonomic group some specimens should be assigned to. Some specimens were originally thought to be jellyfish, but have now been recognised as the holdfast of sessile frondose species. Some species may also be different stages in the life cycle of other species.
