Stromatolite Tumbled Stones, Tumbled Stromatolite Fossil Stone
If you're wanting to add a really really old stone to your collection then a Stromatolite crystal is a perfect choice. Stromatolite is believed to be between 2-3 BILLION years old. We also have Stromatolite in palm stones.
Stromatolites were common in Precambrian time (i.e., more than 542 million years ago). Some of the first forms of life on Earth are recorded in stromatolites present in rocks 3.5 billion years old. Although stromatolites continue to form in certain areas of the world today, they grow in greatest abundance in Shark Bay in western Australia. A matlike layer of blue-green algae is able to grow on the surface of sediments in the shallow waters there because evaporation causes high concentrations of salt that discourage snails and other organisms from eating the blue-green algae.
We're excited to intuitively pick a Stromatolite tumbled stone for you from our inventory. The pictures are a representation of what we have available. Approximate size is 1" - 1.25". The stone you receive may be slightly larger or smaller.
