fossilized6s Posted August 7, 2017 Share Posted August 7, 2017 I went down to a new spot i found to see if i could find more Carboniferous shark teeth. Sadly, no teeth. But i found this oddity. I've personally have never seen anything like it, and it kind of reminds me of shark skin, but i'm leaning more towards a strange trace fossil. In the upper right corner and top center you can see symmetry somewhat in the shape i can only describe as a sunflower shape. Other than that the spots seem random. Any opinoins are welcome. I've been searching and searching without any luck. Thanks, guys and gals This is Carboniferous black shale. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

fossilized6s Posted August 7, 2017 Author Share Posted August 7, 2017 That went through my mind as well. But the spots are too large and not as tightly packed together as cartilage usually is. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
Wrangellian Posted August 7, 2017 Share Posted August 7, 2017 This looks reminiscent of a sort of mud drying/cracking(?) pattern - I forget the name or the explanation but it was discussed here on the forum not too long ago. Here is the photo I showed of an example I found in my local Cretaceous but did not bother to try to collect and it is now gone, and now I wish I had made the effort: 1 Link to comment Share on other sites More sharing options...

Hi Wrangelian, maybe you are referring to counter septarian structures? ciao Link to comment Share on other sites More sharing options...
Rockwood Posted August 7, 2017 Share Posted August 7, 2017 Could also be a feature caused by settling and dewatering of a sediment layer. Often a less permeable capping is being percolated through. Link to comment Share on other sites More sharing options...
Wrangellian Posted August 7, 2017 Share Posted August 7, 2017 Something like that. Link to comment Share on other sites More sharing options...
fossilized6s Posted August 7, 2017 Author Share Posted August 7, 2017 I think you nailed it, Wrangellian. The knowledge passed along on here never ceases to amaze me. Thanks everyone. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

Doctor Mud Posted August 8, 2017 Share Posted August 8, 2017 I agree, I think this looks like some sort of sedimentary structure formed by dewatering of the shale during diagenesis or lithification. Similar structures are in the thread cited by abyssunder. 1 Link to comment Share on other sites More sharing options...
