Description

Stromatolites Stromatolites are multi-layered calcareous structures, formed by thin overlapping layers, resulting from the biotic activity of cyanobacterial colonies. Stromatolites are among the first traces of life on Earth, among the first fossils. They can have a flat, conical, wavy, digital, columnar shape and a porous tubular or fenestrated internal microstructure.

Stromatolites formed in shallow waters with a low sedimentation rate, and helped terraform our planet by removing oxygen from the atmosphere, thus contributing to the explosion of life that followed.

In some areas of the world, such as Bolivia and the United Kingdom, fossilized stromatolites from various geological periods are mined and polished into jewelry and other ornaments. In Australia, in the famous Shark Bay, there are still active modern stromatolite colonies.
