Kim Ellis Posted January 25, 2018 Share Posted January 25, 2018 Hi All, Wondering if you could give me some feedback. Is this a fossil, preservation? Cell plates are visible and imprints. Photos taken wet. Thanks!! Kim Link to comment Share on other sites More sharing options...
izak_ Posted January 25, 2018 Share Posted January 25, 2018 Where was this found? I don't see any fossils here, likely a piece of ironstone. Link to comment Share on other sites More sharing options...
caldigger Posted January 25, 2018 Share Posted January 25, 2018 Kim, what are we calling cell plates? What sort of imprints? I guess the photos aren't showing what you see. Can you elaborate some? Link to comment Share on other sites More sharing options...

doushantuo Posted January 25, 2018 Share Posted January 25, 2018 I must agree with the other opinions:the biogenic origin is not immediately obvious(he said euphemistically) Link to comment Share on other sites More sharing options...
ynot Posted January 25, 2018 Share Posted January 25, 2018 This is an iron concretion. The patterns are from mineral dissolution. I also see no fossils. Darwin said: " Man sprang from monkeys."

ynot Posted January 25, 2018 Share Posted January 25, 2018 Last pic looks the same. Can You post some pictures of it dry? Darwin said: " Man sprang from monkeys."

doushantuo Posted January 25, 2018 Share Posted January 25, 2018 most (body)fossils show meristic/recurring structures ,caused by the dynamics and kinetics of accretionary growth(diffusion of morphogens*),which most of the time results in some form of recognizable(radial or bilateral) symmetry,and/or at least regular spatial patterning. In most fossils of course,the third dimension gets lost,which makes recogniton harder. *mathematically/topologically speaking:Honda trees,Voronoi tiling,Koch curves/fractality,Korn***-Spalding patterns,circular reflectors/(caustics)),Fibonacci structures(PLANTS!) ***Not anything to do with the band edit(hours later): in the first sentence changed "patterns" to "structures" Link to comment Share on other sites More sharing options...
Ludwigia Posted January 25, 2018 Share Posted January 25, 2018 I agree with the others. Please describe "cell plates" and "imprints" in your own words and tell us where you found it. Just showing us photos isn't enough, since all we are seeing, even on the closeups, is an iron concretion. Greetings from the Lake of Constance.

Rockwood Posted January 25, 2018 Share Posted January 25, 2018 It's not a coincidence that patterns like those in concretion resemble life forms. Life forms, the hard parts that are likely to fossilize in particular, are essentially the genetic taming of the same sort of physical processes.

MeargleSchmeargl Posted January 25, 2018 Share Posted January 25, 2018 Totally geological. Every single fossil you see is a miracle set in stone, and should be treated as such. Link to comment Share on other sites More sharing options...
