Dickinsonia is an enigmatic Ediacaran organism that lived about 560 to 550 million years. Had stripes or segments in the body. His identity is controversial, some think it was a flat and segmented worm, others that it was a soft coral, and some believe it was a jellyfish, many have argued that even were lichens.
Ediacáricos agencies, also known as Ediacaran biota period or biota or wildlife vendiense ancient life forms are sessile tubular shaped leaf that inhabited the Earth during the Ediacaran period (635-542 million years ago) and organizations representing oldest known complex multicellular. Appeared shortly after the Earth after the extensive thaw and Cryogenic last glacial period, and largely disappeared shortly before the rapid appearance of biodiversity known as the Cambrian explosion, which consisted of the first appearance in the fossil record basic morphologies patterns and later form the basis of modern animals. Few elements of the diversity of organisms ediacáricos be incorporated into these patterns, and the various agencies of the Cambrian moved and completely replace the life forms that had dominated the Ediacaran fossil record.
