Stromatolite Fossils for Sale

Stromatolite Fossils for Sale – Stromatolites are layered sedimentary formations created by algae or cyanobacteria. Both produce a sticky substance that binds sand and rocks to form a mat that they grow on in colonies. They do this layer after layer and form the microbial mats that could grow as much as a meter tall. When these stromatolite colonies are sliced longitudinally the beautiful layers are exposed and can be quite stunning.
