The Ediacaran Fauna probably doesn't belong to a new kingdom though. That seems less likely given the expansion of our fossil discoveries. Instead there appear to be some ancestral organisms (like the fossil Kimberalla being an ancestral mollusk) and some of the weirder ones (like the Dickinsonia you posted) are kind of a hollow sac of single-celled organisms behaving as a multicellular colony (maybe like a slime-mold does?).
