Dickinsonia is an iconic organism of the Ediacaran fauna, which are among the first known representatives of multicellular life on the planet. Dickinsonia appears as a ribbed oval with glide symmetry. Dickinsonia was resistant to compaction by overburden, like fossil lichens such as Spongiophyton and Thucomyces, and more compaction-resistant than fossil logs, jellyfish or worms. Dickinsonia also shows indeterminate growth like lichens, fungi, plants, xenophyophorans and colonial animals. Dickinsonia is a genus of extinct organism that lived during the late Ediacaran period in what is now Australia, China, Russia, and Ukraine. It had a round, approximately bilaterally symmetric body with multiple segments running along it. Taking to the warm shallow seas as early as 570 million years ago, these soft and squishy misfits were Earth's earliest complex life. One of the most famous of the lot is Dickinsonia. This...
