Stromatolites are fossilized layered deposits of algae within ancient sedimentary rock. These old single-celled organisms are believed to be some of the first forms of life on this planet. Some cyanobacteria (algae) in the rock dates back over 3.5 billion years. Stromatolites range in a variety of colors and can contain many impurities within the bedrock (which is usually limestone). The most common colors we’ve encountered are brown, beige, reddish-brown, yellow, white, and grey. Stromatolites can be found all over the world, with an abundance located in Morocco, Australia, Canada, the United States, as well as the northern European and Baltic states.
