5 Inch Stromatolite Sphere. Stromatolites are fossils of laminated rock formed from the layer-by-layer buildup from microbial mats of cyanobacteria over thousands of years. Stromatolites formed the very first macro fossils found in the fossil record going back several billion years. This beautiful 5" sphere from Bolivia's eastern Andes, weighs over 6 pounds and is roughly 2.3 billion years old. The fossilized dark brown rock was cut and polished and contains many tan and lighter brown fossilized cyanobacteria colonies, resembling concentric oval rings on top and wavy concentric layers all along the side of the sphere; making the overall appearance to be like that of a strange planet. A small display ring is included to help showcase this spectacular piece.
Estimated Value $400 - 500.
