12 Facts About Ediacaran biota

Multiple hypotheses exist to explain the disappearance of this Ediacaran biota, including preservation bias, a changing environment, the advent of predators and competition from other life-forms.

Martin Glaessner proposed in The Dawn of Animal Life that the Ediacaran biota were recognizable crown group members of modern phyla, but were unfamiliar because they had yet to evolve the characteristic features we use in modern classification.

Ediacaran biota believed that they independently evolved a nervous system and brains, meaning that "the path toward intelligent life was embarked upon more than once on this planet".

Adolf Seilacher has suggested the Ediacaran biota sees animals usurping giant protists as the dominant life form.

Seilacher has suggested that the Ediacaran biota organisms represented a unique and extinct grouping of related forms descended from a common ancestor and created the kingdom Vendozoa, named after the now-obsolete Vendian era.

Ediacaran biota later excluded fossils identified as metazoans and relaunched the phylum "Vendobionta".

Ediacaran biota described the Vendobionta as quilted cnidarians lacking stinging cells.

Mark McMenamin saw such feeding strategies as characteristic for the entire Ediacaran biota, and referred to the marine Ediacaran biota of this period as a "Garden of Ediacara".

Ediacaran biota argues that the fossils are not as squashed as known fossil jellyfish, and their relief is closer to compressed woody branches whose compaction can be estimated as compressed cylinders.

Thin sections of Ediacaran biota fossils show lichen-like compartments and hypha-like wisps of ferruginized clay.

Constituents of this biota appear to survive through until the extinction of all Ediacarans at the base of the Cambrian.

One interpretation of the Ediacaran biota is as deep-sea-dwelling rangeomorphs such as Charnia, all of which share a fractal growth pattern.
