Fossilized sponge.
Glass sponge reefs were thought to have gone extinct about 40 million years ago, leaving behind giant fossil cliffs that stretch across parts of Spain, France, Germany, and Romania. In 1987, however, a team of Canadian scientists discovered 9,000-year-old living glass sponge reefs on British Columbia’s northern coast.

Skeletonization doesn't apply to sponges, so when they first emerged remains a mystery.

Fossils are the traces or remains of organisms buried and preserved in sediments. They consist not only of hard body parts, such as bone and shell, but also may be impressions of plants, or tracks, trails, and burrows. Fossils can tell us what life was like on Earth in ancient geologic time, helping geologists describe ancient depositional environments and understand past climates. Fossils ...
