Scylla Posted March 24, 2012 Share Posted March 24, 2012 (edited) I wish I knew more about this picture I stumbled upon on while surfing the interwebnet. I can see cell nuclei! http://botweb.uwsp.e...ges/SEM0291.htm Edited March 24, 2012 by Scylla Link to comment Share on other sites More sharing options...

Kehbe Posted March 24, 2012 Share Posted March 24, 2012 I have collected a good bit of petrified wood and have been told many times that if i want accurate ID on most pieces that it must be done at the cellular level with a cut across the grain and polished surface. Unfortunatly, most of the wood I have will have to remain unidentified until I get myself an electron microscope and a slabber saw! Cool pic, thanks for posting! It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.

painshill Posted March 24, 2012 Share Posted March 24, 2012 Yes, it is cool isn't it. There's an interesting item here about identification of petrified wood: http://www.evolvingearth.org/learnearthscience/sciencearticles0809identifypetrifiedwood.htm Roger I keep six honest serving-men (they taught me all I knew);Their names are What and Why and When and How and Where and Who [Rudyard Kipling] Link to comment Share on other sites More sharing options...
xonenine Posted March 24, 2012 Share Posted March 24, 2012 (edited) the photos in the following PDF are not electron scanned, but these many pet wood samples from Chickaloon are highly magnified... forum thread: http://www.thefossil...post__p__224044 PDF - direct link Edited March 26, 2012 by xonenine "Your serpent of Egypt is bred now of your mud by the operation of your sun; so is your crocodile."

Fruitbat Posted March 26, 2012 Share Posted March 26, 2012 Actually...having had a bit of experience with electron microscopy...I'm reasonably positive that the initial picture in the post WAS taken using a Scanning Electron Microscope (SEM). -Joe Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...

erik m Posted March 26, 2012 Share Posted March 26, 2012 The photo's you see here are done with a normal microscoop. Link to comment Share on other sites More sharing options...
ashcraft Posted March 26, 2012 Share Posted March 26, 2012 I was once told by a museum curator who should be in the know, that petrified wood is actually mineral-fill phenomenon, not a mineral-replace phenomenon. He contended that if you treated petrified wood with hydrofluoric acid, it would dissolve all the mineral, and leave a fine cellulose "bone" structure. I think these photos lend credence to that.
