Could this be a crab claw? Alabama


Recommended Posts

Found last week in small stream in my yard south of Bham, AL which contains mainly early/mid Paleozoic era and potentially some late.  This specimen resembles a crab fossil specimen from AL, but the time period doesn’t match up.  Encyclopedia of AL
Thus, what could it be? IMO, does not resemble the pics I find for Eurypterus pinchers. 

 Another possibility is that it could have been mixed in with landscape river rocks  rocks uphill from the stream?

Oops - I went to print a new ruler & forgot to add. Roughly 5cm x 2cm x 2.5cm. Photo added.  Thanks for looking.

Looks like an ironstone concretion or some similar geological object to me.

Ironstone would make sense here. I can see how this could have formed around another stone to get that shape and it feels like iron. The tapered segments and little bumps reminded me of marine orgs and threw me. Thanks for your help!

If I had a nickel for every piece of ironstone I picked up thinking it was something I would almost be rich. :)
