Dickinsonia: Is an extinct genus of

Dickinsonia is an extinct genus of early multicellular organisms that lived during the late Ediacaran period, around 560 million years ago. These organisms are significant for their unique body plan and provide insights into the evolution of complex life forms, marking a crucial point in the evolutionary history of the animal kingdom. 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 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. For Dickinsonia, at least, scientists can now argue these strange soft-bodied beings were the progenitors of the Cambrian animals that swept over the planet, and thus were our ancestors.
