Butterstone is from the Greenstone belt of South Africa. The dark green lines contain the earliest known life forms found on Earth which are Blue – Green Algae we call them Stromatolites.

FYI: Stromatolites are domed limestone structures that have compact, curving layers. “Live” fossils were formed when grains of sediment were trapped on the algaeā€™s sticky surfaces. That is why you see the curvy lines which is a result of laminated domes and multiple layers of mineral replacements. Even though stromatolites developed in an environment lacking in oxygen they produced and released vital oxygen which became an abundant gas in the atmosphere for the first time. Stromatolites vary in size from a few centimeters to three feet in diameter.
