Aug 2, 2021 · Turner's opinion is that if sponge fossils were turning up before and during the Cambrian period — during which there was an explosion of living things that were able to form their own skeletons — they must have first evolved much earlier than that. Skeletonization doesn't apply to sponges, so when they first emerged remains a mystery.
