FIGURE 4 – Stromatolites are rock-like structures formed by layers of fossilized bacteria. Dating as far back as 3.4 billion years ago, they are the oldest evidence of life forms on Earth. Ancient bacteria in water produced thin sheets of film that trapped mud. Over time, these thin sheets formed microfossils—fossils too small to see without a microscope. Eventually, the sheets built up into the layers you see here.
