William Posted July 26, 2016 Share Posted July 26, 2016 I believe this is mudstone. Take a look at the bubble. I suppose there's air in there from around 300,000,000 million years ago. Link to comment Share on other sites More sharing options...
CraigHyatt Posted July 26, 2016 Share Posted July 26, 2016 Wonderful thought, but most of the gaseous elements (except maybe nobel) would likely have reacted with the rock. Might be a few atoms rattling around in there. Try shaking it next to your ear. ;-) Info: Craig Hyatt, retired software/electrical engineer Experience: Beginner, fossil hunting less than a year Location: Eagle Pass, TX USA on the border with Mexico, hot dry desert Formation: Escondido, Marine, Upper Cretaceous Materials: Sandstone, Mudstone, Shale, Chert, Chalk Typical: Thalassinoides, Sphenodiscus, Exogyra, Inoceramus Reference: http://txfossils.com/Txfossils.html Link to comment Share on other sites More sharing options...

CraigHyatt Posted July 26, 2016 Share Posted July 26, 2016 Yep, definitely heard a few rattling around. I wouldn't have thought it possible, but I did a search and got a few hits on air trapped in rocks.... even billion year old rocks. So maybe you are right.

DPS Ammonite Posted July 26, 2016 Share Posted July 26, 2016 That is an iron rich concretion not a gas bubble. Samples of gas are usually only captured inside single crystals of minerals such as quartz and zircon that don't allow easy escape of trapped gas. My goal is to leave no stone or fossil unturned.

JohnJ Posted July 26, 2016 Share Posted July 26, 2016 Keep in mind, that rock is permeable. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Raggedy Man Posted July 26, 2016 Share Posted July 26, 2016 What's wrong with the 5 billion year old oxygen you're breathing in now? Does it smell funny? Lol Sorry.... ...I'm back. Link to comment Share on other sites More sharing options...

doushantuo Posted July 26, 2016 Share Posted July 26, 2016 THis has NOTHING to do with the foregoing,and is fascinating: http://faculty.washington.edu/dcatling/Som2012_Raindrop_Imprints_incl_Suppl.pdf Link to comment Share on other sites More sharing options...
doushantuo Posted July 26, 2016 Share Posted July 26, 2016 I believe there are gas bubbles in Mesoproterozoic Vindhyan stromatolites,about 1 GY old. Which is,of course not the same as atmospheric oxygen. In essence they are the fossilized farts of microbial mat Archaea Fascinating ,i know,and irrelevant as heck for the present discussion Link to comment Share on other sites More sharing options...
doushantuo Posted July 26, 2016 Share Posted July 26, 2016 and this has at least a teeny weeny bit to do with all of the foregoing: http://www-math.mit.edu/~bush/GeoBiology.pdf Link to comment Share on other sites More sharing options...
