Sponge fossil record in the Neoproterozoic–Cambrian transition: are sponges part of the Cambrian radiation? Animal phylogeny indicates that sponges (or stem-group sponges) must be among the earliest animals.Jul 28, 2021 · Sponges are the most basic known animal type 2,3; it is possible that body fossils of hitherto-undiscovered Proterozoic metazoans might resemble aspect(s) of Phanerozoic fossil sponges. Sponges are very simple animals which live on the sea floor. They still exist today, and the earliest known fossil sponges are 580 million years old. The silica fills the gaps in the sponge’s skeleton and, over millions of years, the skeleton itself can dissolve away and be replaced by other minerals.If the sponge broke down but the salt remained and held its shape, we would call that a permineralized fossil of the sponge.
