New find !!!
Stromatolites are fossilized carbonate structures.
These are among the oldest known fossils, dating back to 3.5 Ga (in Australia). They were formed by cyanobacteria (“blue-green algae”). Using the sun to harness energy, they produced and increased the oxygen content of the earth’s atmosphere to around 20%, enabling life to flourish.
These 25 million-year-old stromatolites were found in France, in the heart of the city of Clermont-Ferrand, at the summit of a volcano called Montjuzet.
Some stromatolites are even mixed with lava !
