    www.britannica.com/science/stromatolite

    stromatolite, layered deposit, mainly of limestone, formed by the growth of blue-green algae (primitive one-celled organisms). These structures are usually characterized by thin, alternating light and dark layers that may be flat, hummocky, or dome-shaped.

    Stromatolites are layered accretions of microorganisms, primarily cyanobacteria, mixed with sedimentary grains. These formations often occur in shallow water environments. They are one of the earliest forms of life on Earth that existed well before more complex organisms appeared.

    Stromatolites are living fossils and the oldest living lifeforms on our planet. The name derives from the Greek, stroma, meaning “mattress”, and lithos, meaning “rock”. Stromatolite literally...

  6. Stromatolites are layered structures formed by the growth of cyanobacteria (formerly called blue-green algae) in shallow water environments. These microbial mats trap and bind sediment, creating distinct layered structures that can range from centimeters to meters in height.
