sTamprockcoin Posted June 7, 2019 Share Posted June 7, 2019 Yesterday I broke up a small boulder from an area my town filled in with rock from a nearby road project. I believe that this is Marcellus or Harrell/Brailer Shale. The item pictured is about 2 inches long and completely filled with very pretty little pyrite cubes. Can anyone tell is this an in filled worm burrow or a a filled Crinoid stem? Both things were in other parts of the same boulder. The item in the third photo i cant decide if its a "brach" or a "trilo-bit"? Anyone want to hazzard a guess. 1 “Beautiful is what we see. More beautiful is what we understand.

CSimpson176 Posted June 8, 2019 Share Posted June 8, 2019 Honestly looks like a bryozoan to me, especially seeing how the bottom of it ends abruptly and really just the general morphology. Don't see any places that would suggest columnals on it to be a stem. I honestly was having trouble with the third photo as I couldn't tell whether it was a brachiopod, pygidium or partial cephalon of a trilobite. Thanks @piranha! 1 Link to comment Share on other sites More sharing options...
sTamprockcoin Posted June 8, 2019 Author Share Posted June 8, 2019 Cool, thanks I hadn't thought about bryozoan. 1 “Beautiful is what we see. More beautiful is what we understand. Most beautiful is what we do not comprehend.” N. Steno Link to comment Share on other sites More sharing options...
Rockwood Posted June 8, 2019 Share Posted June 8, 2019 In this context I think pyritized poop should be considered. The configuration could be seen as burrow fill as easily though I suppose. 1 Link to comment Share on other sites More sharing options...
sTamprockcoin Posted June 8, 2019 Author Share Posted June 8, 2019 Pyritized Poop sounds painful - too much iron in the diet?! (Sorry, I just couldn't resist!) Hmmm I'll have to set this one aside until my local mineral society starts its meetings in the fall and I can show to some local experts. 2 “Beautiful is what we see.

Rockwood Posted June 8, 2019 Share Posted June 8, 2019 I'll tag our poopers just in case. @Carl @GeschWhat 2 Link to comment Share on other sites More sharing options...

Unfortunately, it is difficult to determine whether "poo'ls gold" has fecal origins. In this instance, IMHO, I say it is more likely evidence of burrowing. 2 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...

sTamprockcoin Posted June 10, 2019 Author Share Posted June 10, 2019 Have they left you any (fool's) golden eggs? 1 “Beautiful is what we see. More beautiful is what we understand. Most beautiful is what we do not comprehend.” N. Steno Link to comment Share on other sites More sharing options...
sTamprockcoin Posted June 10, 2019 Author Share Posted June 10, 2019 Thanks I shall label this as a pryitized burrow! 1 “Beautiful is what we see. More beautiful is what we understand.
