Where are stromatolites still formed by bacteria today?
Quick Answer
Living stromatolites are found in a few places with shallow, salty waters, especially Shark Bay in Western Australia. They are built by microbial mats, mainly cyanobacteria.
The Full Story
Modern stromatolites are still forming in a small number of environments, most famously in Shark Bay, Western Australia. There, cyanobacteria and other microbes trap and bind sediment, creating layered structures over time. Stromatolites are important because ancient fossil versions are among the earliest evidence of life on Earth, dating back more than 3 billion years. Their survival today depends on conditions that limit grazing by animals and keep the waters unusually saline. Shark Bay’s living stromatolites are among the world’s best-known examples of microbial construction.
