Gorgeous little brown, black and grey fossil Stromatolite tumblestones; an ancient layered mound of bacteria which formed the first fossilised life on Earth at around 3.45 Billion years old!
They converted carbon dioxide, sunlight, and sea water into Oxygen, which contributed vastly to the Earths breathable atmosphere.
Some modern day Stromatolites can be found in Shark Bay, Australia; but fossil examples can be found across much of the world, including the UK, Australia, Peru, Bolivia, Russia, and India – bear in mind, when these mounds grew, most of the Earths surface was underwater.
These pieces make a great decorative stone and talking point; whether you’re a fan of fossils or tumblestones!
