1" North Pole Dome Stromatolite Section - 3.49 Billion Years

North Pole Dome Stromatolite Section - Billion Years #154979

This is a 1" wide section of a rare North Pole Dome Stromatolite from Western Australia. Until very recently these Stromatolites were thought to be the oldest known stromatolites, dated to approximately 3.49 Billion Years, slightly older than the Strelley Pool Stromatolites. In 2016 the discovery of potential trace fossils left by 3.7 Billion Year old Stromatolites in Greenland was announced. But some scientists still are debated whether these Greenland trace fossils were left by Stromatolites, or if they are organic in origin at all.

About Stromatolites

Stromatolites are fascinating, ancient rock formations created by the activity of cyanobacteria and other microorganisms. These layered, mound-like structures represent some of the earliest evidence of life on Earth, dating back over 3.5 billion years. Often found in shallow, warm waters, stromatolites form as layers of sediment and minerals are trapped and bound by microbial mats, gradually building up over time into unique, textured shapes.

Visually, stromatolites can range from smooth, rounded forms to intricate, banded structures, with colors that span earthy reds, browns, greens, and grays. Each layer captures a record of environmental conditions at the time of its formation, making stromatolites an invaluable source of information for scientists studying Earth’s early history and the origins of life.

Today, fossilized stromatolites are highly prized by collectors, both for their scientific significance and their natural beauty. Some living stromatolites can still be found in a few rare locations around the world, such as Shark Bay in Australia and certain alkaline lakes.
