Puzzling soft bodied fossils known as both ediacaran fossils and also as vendozoans are found in rocks of late Proterozoic age ( approx. 600 million years). Originally thought to be soft bodied representatives of living phyla, they are now thought by many paleontologists to have been some sort of evolutionary "experiment", possibly representative of some form of symbiosis between cyanobacteria and a eukaryotic life form. Some have suggested marine lichens as a model with modern lichens being a reminant of what was once a major ecosystem of the Precambrian earth.
