[Note Guidelines] Photographer's Note
This beautiful fossilized fern is about 8 cm long and can be seen in a piece of roughly hewn sandstone paver purchased from a local nursery. The charcoal grey of the fern forms a very distinct pattern in the multi colored brown and beige sandstone. It is probably millions of years old and yet, it is still so perfect. Another fine example of the wonders of nature!

Hi
It is not fossil fern It is a manganese oxide It is not a fossil. Maybe it is not pefectly sharp but probably first time on TN

Hi Lyndall, being a Sr. Staff Scientist by profession and seeing this effect before, I believe cataclysta is correct... manganese oxide can form dendritic patterns on the surface of sandstone that look incredibly like a fern. Its easy to understand how one could be fooled. That being said it is still a singular element of nature and interesting to see. I enjoy macro photography. IMO your composition, exposure and detail are excellent. TFS and Warmest Regards. Thomas

It really is a fine composition in stone Lyndall, but I share Krzysztof's opinion, the fossil like structure is the result of seeping solutions rich in mineral Pyrolusite, a manganese dioxide.
Cheers,
Mehmet
