Fossil sea sponge.

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.E.C. Turner. By Marion Renault. July 28, 2021.
