Vae70 Posted January 10, 2021 Share Posted January 10, 2021 Found this today out at the brooks, stumped on what it could be - never seen this kind of patterning on anything from the brooks before. Perhaps some sort of armor plate? Link to comment Share on other sites More sharing options...

PaleoNoel Posted January 10, 2021 Share Posted January 10, 2021 That is an odd piece for sure. The brooks are well known for producing concretions which frequently resemble fossils or sometimes the ironstone replaces a fossil (I found the mold of a bivalve preserved that way a few years ago). I've picked up a few pieces similar to yours and had put them away with others which I believed to be geologic in origin. If it is a fossil, my guess would be sponge, but I'm not as familiar with inverts. Lets see what others have to say. @Trevor@njfossilhunter@The Jersey Devil 1 Link to comment Share on other sites More sharing options...
hemipristis Posted January 10, 2021 Share Posted January 10, 2021 what an interesting piece! The first photo had me thinking fish pharyngeal plate, but the back said looks nothing like what I'd expect such to be. I'm stumped 'Those who cannot remember the past are condemned to repeat it.'

Rockwood Posted January 10, 2021 Share Posted January 10, 2021 Are those dark pieces mixed in it hematite ? It would tend to boost the ironstone concretion idea. 1 Link to comment Share on other sites More sharing options...

frankh8147 Posted January 10, 2021 Share Posted January 10, 2021 I think this is a really cool-looking concretion. They form all kinds of cool patterns! 1 Link to comment Share on other sites More sharing options...

I agree with this; your find is a concretion, albeit an interesting one. : ) Link to comment Share on other sites More sharing options...
