[Note Guidelines] Photographer's Note
Hi Folks , still carrying on with photos taken in the Drumheller Badlands I have today a simple rock.

while walking along one of the valleys , I found this are of stones , and in it was old remains of what I imagine was likely lichen. of course I have no idea of the age of this stone or the fossil remains printed on it , really I did not find it too important to the idea.

the idea being just to display a remnant from the past which had become imprinted in this stone , to travel its way through time to evidence its existence to us now. though I did not gather any such stones or remove them from the area , I did pick it up to feel it this is not a growth on the stone but a fossilized remains imprinted in it , there where many stones in this general area that showed this colored pattern , what exactly it is , and when it became trapped in this stone is really the work of paleontologists. to me it was another one of the things in this imagination inspiring place that struck me as interesting.

regards
Art

hi art,
good to see something fossilised, ofcourse only an expert will appreciate this. you could have shown this little closer to admire. tfs.

Hi Art, these may look look like "plant" origins, but can also be attributed to a process of chemical reaction causing "dendrites" in the stone, also leaching and other chemical processes in rock can give the impression of fossils. These pseudofossils form as naturally occurring fissures in the rock and are formed by percolating mineral solutions. They form when water rich in manganese and iron flows along fractures and bedding planes between layers of limestone and other rock types, depositing dendritic crystals as the solution flows through. A variety of manganese oxides and hydroxides are involved. very interesting though, I like this a lot...
