Rob Russell Posted June 2, 2012 Share Posted June 2, 2012 Hey Folks! Glad things are back up and running again. A few weeks ago I had the opportunity to hunt an old coal mine spoils pile for some mazon creek nodules. It was a two day hunt, and I gave it about 5 hrs each day. i collected just short of 1,000. I'd be greatful if anyone would be willing to share any insight as to what has worked best using the freeze/thaw method. Thanks for any suggestions. Here's a pic of the nodules. My buddy stopped by after work and snapped the shot from my garage roof. Finding my way through life; one fossil at a time. Link to comment Share on other sites More sharing options...

Roz Posted June 2, 2012 Share Posted June 2, 2012 I would think out of that many you should hatch some really nice fossils! I can't wait to see when they open. Welcome to the forum! Link to comment Share on other sites More sharing options...

Rob Russell Posted June 2, 2012 Author Share Posted June 2, 2012 Thanks everybody for your comments. And thank you, Carl, for the link to the Richardson's Guide. I had been told to freeze for a week, but I'm definitely liking the 2 day idea much better! And that big number "25." I wasn't sure what to expect as far as how many cycles it could possibly take. I figure I'll be freezing nodules for 3-4 years. Until I go collect more. Finding my way through life; one fossil at a time. Link to comment Share on other sites More sharing options...
glacialerratic Posted June 3, 2012 Share Posted June 3, 2012 Nice report! Have you opened any of them yet? Link to comment Share on other sites More sharing options...
Rob Russell Posted June 3, 2012 Author Share Posted June 3, 2012 Hey Tim. Actually, I found some that were already open, and coaxed a few into opening that were almost split. I also found some, what appear to be, cephalopod (?) parts. Some corals perhaps? Bottom line... nothing to exciting yet; however, I will take some pictures and post, because my purplish blob could be a rare one. Finding my way through life; one fossil at a time.

snakebite6769 Posted June 3, 2012 Share Posted June 3, 2012 I had a chance to go to Mazon Creek when I was working at Braidwood station, I have a large number of nodules also. Im still freeze thawing them. I have found that the best way is to place the nodules in a large bucket and let it fill with rain water as it works a lot better than tap water. too much stuff in Tap water, let it sit in the water for two days, and then take out of the water and place in a shallow container with some water, just enough to cover the nodules, and freeze for two days, then let it thaw at room temp, tap the sides of it with another nodule after a couple cycles and they will pop right apart. Good luck Rob! Link to comment Share on other sites More sharing options...
