They are usually classified along with other sponges in the phylum Porifera, but some researchers consider them sufficiently distinct to deserve their own phylum, Symplasma. Possible sponge body fossils has been proposed from the Ediacaran, although poor preservation suggest prevents definitive identifications. Other evidence of biomarkers and loose spicules date further back to the Cryogenian (720-635 million years ago), but without additional evidence, it’s difficult to say if these came from early sponges or ...
