Monica Posted March 17, 2019 Share Posted March 17, 2019 Hi everyone! Today I have something different to show you all: Mazon Creek area nodules that have opened for me via the freeze-thaw method!!! These unopened nodules were acquired from @deutscheben after I asked him if he wouldn't mind sending me some since I wanted to try my luck at opening them myself. He generously sent me 18 unopened nodules, all of which have gone through the freeze-thaw cycle I don't know how many times and so far only 3 have opened up. I'd like a little help in identifying what they are - thanks in advance!!! I believe they are from the Pennsylvanian period of the Carboniferous - any and all help/suggestions are appreciated!!! Monica Nodule #1, both pieces: I believe this is an Annularia sp.: Nodule #2, both pieces: Perhaps bark or Cordaites sp.? By the way - do you think I should put the bigger piece back through freeze-thaw to see if it opened up some more? More to come... 2 Link to comment Share on other sites More sharing options...

Nimravis Posted March 17, 2019 Share Posted March 17, 2019 @Monica looks like a Cyclus americanus. NIce finds. 4 Link to comment Share on other sites More sharing options...

deutscheben Posted March 18, 2019 Share Posted March 18, 2019 Outstanding, I'm so happy you got some identifiable fossils out of your concretions! I agree with your Annularia ID for the first one, the second looks a lycopod leaf Cyperites , and I think Ralph is right with the third one. Other than popping the last little bit covering the far left of the leaf on the second one I don't think there is anymore to reveal- you could try tapping the end with a hammer to get it off. I hope more freeze-thawing will split some additional ones open for you in the future! 1 Link to comment Share on other sites More sharing options...

I've never heard of Cyperites before, so that's definitely a new one for me, too - yay!!! I'm very happy with what has popped open so far - I'll tag you when more pop open to let you know if any more of the nodules contain little fossil goodies... Thanks again so much!!!
