  3. Image 16.2. Modern stromatolites, Bahamas

  4. Image 16.3 Cambrian stromatolites

  5. Modern stromatolites grow in the intertidal zone. Ancient stromatolites form columns. A cross section reveals layering similar to that seen in ancient stromatolites. Microbes live on the surface of the stromatolite. Sediment is deposited on the microbes,... ...which grow upward through the sediment, forming a new layer. Image 16.3. Building microbial mats (stromatolites)
