Comb jellies, which look like miniature jellyfishes, use rows ...Some sponges produce a skeleton made of silica (the hard substance that sand is usually made of). When sponges fossilise, the silica sometimes dissolves and then forms flint. This rock sometimes preserves fossils, including other sponges. So you can often find fossil sponges on beaches where most of the pebbles are made of flint.A genetic analysis of ancient sea sponges has provided the oldest evidence of animal life. Researchers studied an unusual chemical in rocks from 650 million years ago. They found that it was probably produced by sea sponges, rather than algae as was previously thought.
