Stromatolites for Sale


Stromatolites Geological Time: Paleocene Size: 165mm X 110mm X 95mm thick Fossil Site: Flagstaff Formation, Utah County, Utah Item: OFS026 Price: $125.00 Remarks: The second picture shows the uncut naturally weathered back of this specimen. Stromatolites were formed by prokaryotic, photosynthetic bacterial, most likely cyanobacteria, the primitive organisms that largely produced Earth's atmospheric oxygen). This individual colony has been polished exhibiting the growth rings. This stromatolite dates to the Paleocene ~ 60 million years ago when stromatolite was no longer prevalent and abundant. By the Cambrian, photosynthetic bacteria responsible for the biogenic formation of stromatolite structures no longer had the earth to themselves. The oxygenated atmosphere had become toxic to some bacteria, and they had to compete with other organisms, some of which would have been predaceous to this most ancient of life forms.
