Vendozoans (or ediacaran fossils) are considered by some paleontologists to possibly
be a type of marine lichen. Essentially an "evolutionary experiment, these life forms appear
to have dominated the Earth some 600 million years ago during the very last part of the
Proterozoic Era. Lichens living today in this viewpoint, represent a vestage of this once
dominant ecosystem.
