One paper by Antcliffe, et al., (2014) discusses 20 potential candidates for being the oldest Porifera fossil found. Further evidence for the early evolutionary presence of sponges came from typical metabolites produced by these animals and discovered as ‘molecular fossils’ in rocks and oils from the Neoproterozoic (660–635 million years ago), more than 100 million years before the Cambrian explosion of animal diversity, including sponges, appeared in ...
