🔎 UNIDENTIFIED Need help IDing some rocks.

[kray]

Hi all,
Wondering if anyone can ID these rocks. They were found by my mother in law in the Farmington River in Ct. I think they’re weathered sandstone. She says they’re clay formations.
Thanks for any help!

No idea but they look cool

They could be concretions. Break one apart.

Your mother-in-law is pretty much correct. They're 'mudstone' concretions, often formed in fine-grained sedimentary deposits and usually carbonate cemented.

Mother-in-laws are always correct. Or at least that's what I'm told. :O
