pediabrown Posted November 22, 2016 Share Posted November 22, 2016 This was found in Pahrump Nevada. Can anyone tell me what it is? Please? Link to comment Share on other sites More sharing options...
doushantuo Posted November 23, 2016 Share Posted November 23, 2016 yep. Dendrites,probably manganese ones. Which means:non-biological in origin Link to comment Share on other sites More sharing options...
Fossildude19 Posted November 23, 2016 Share Posted November 23, 2016 Welcome to the Forum. I agree - Dendrites. Commonly mistaken for plant fossils.

fifbrindacier Posted November 23, 2016 Share Posted November 23, 2016 I, too, agree with dendrites. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

tmaier Posted November 23, 2016 Share Posted November 23, 2016 Well, I have to disagree. I think it is a diffusion-limited aggregation. OK, that's the same thing as a dentritic mineral deposit, but... it's longer and sounds pretty cool. https://en.wikipedia.org/wiki/Diffusion-limited_aggregation These are fractal patterns created by the ionic forces of the atoms and molecules aligning themselves (combined with some stochastic randomness) and you can find software out there on the internets for making different moss/tree patterns like these. Frost is a similar effect. 3 Link to comment Share on other sites More sharing options...
Ridgehiker Posted November 23, 2016 Share Posted November 23, 2016 Years ago we collected trilobites and inarticulate brachiopods near Pahrump...in thick shale layers towards the California side. Also, the areas northeast of you are filled with excellent deposits of Carboniferous invertebrates. Its hit and miss. Most rock exposures can be sterile and the next be full of fossils eroding out Link to comment Share on other sites More sharing options...
fossiling Posted November 25, 2016 Share Posted November 25, 2016 these cute dendrites are ichnofossils. now thats a beautiful specimen! Keep looking! They're everywhere! Link to comment Share on other sites More sharing options...
abyssunder Posted November 25, 2016 Share Posted November 25, 2016 not a fossil or ichnofossil, but a nice pseudofossil " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
