Dickinsonia is an unusual organism from the Ediacaran biota of Australia. Scientists have yet to discern what it is and have previously identified it as a jellyfish; coral; polychaete worm, worms with protuberances on its sides (although it lived too early to be classified with them); turbellarian, a subdivision of Platyhelminthes (flatworms); mushroom; xenophyophoran protist, a large unicellular protist; sea anemone; lichen; and relative of chordates.
