fowells Posted January 4, 2013 Share Posted January 4, 2013 We had a big rain last week so I decided to go to a well known site in Runaway Bay to see what had been newly exposed. Found some nice examples of the normal stuff and then caught sight of something I thought at first was a piece of glittery, foily trash. On closer inspection, it turned out to be an otherwise normal reddish limonite nodule on the outside with beautiful fire on the inside. I used 2 cameras trying to get a photo of what I was seeing. The cellphone camera just would not show any color - that photo is just to show scale (that's a 24 oz coffee cup lid) and some of the other stuff I found out there. The other camera picked up some color but still doesn't do it justice. It was cold and I headed back to the truck when my boots weighed 12 lbs. The nodules of Lake Bridgeport never cease to surprise and delight. I've found them with all manner of interesting interiors, but I never expected to encounter the Schiller Effect on a hunt for Pennsylvanian fossils.

Auspex Posted January 4, 2013 Share Posted January 4, 2013 Neat nodule! The fiery material resembles the prismic display of fossil aragonite; does it appear that there may be some shell there?

fowells Posted January 4, 2013 Author Share Posted January 4, 2013 Auspex, There was no evidence of any fossil in this nodule. I'll look at it again with a glass and confirm. Thanks, danwoehr. Link to comment Share on other sites More sharing options...
Wrangellian Posted January 4, 2013 Share Posted January 4, 2013 It's got to be a piece of aragonite shell (not a complete recognizable shell, just a piece), I'm not sure if there is any other process that something like this would form.. anybody?

fowells Posted January 5, 2013 Author Share Posted January 5, 2013 Quick research indicates aragonite is rare in fossils this old? Link to comment Share on other sites More sharing options...
Wrangellian Posted January 6, 2013 Share Posted January 6, 2013 I think so, yes, but not nonexistent. Link to comment Share on other sites More sharing options...
