Hello, I just recently joined the group and I am hoping for some help on this fossil. Other than the photos, I can't offer any information on it. About 20 years ago I was at an estate sale, in an old home, and spotted a rock up on the foundation in the basement. Upon retrieving it and blowing off the layers of dust and dirt, I found this fossil. I asked if it was for sale, and bought it for a dollar. The texture on the fossil has caused my imagination to wander, but I have no idea what it might be or where it came from. Any information is much appreciated. Thanks.

Welcome to the forum!

 

i can’t help in your ID but it looks pretty interesting. Someone will be along soon with an ID. Best I can do is say with a little confidence is that it’s fauna rather than flora. Looks cool whatever it is. :)

Reminds me of a paleozoic shark tooth? Although I'm not sure I've ever seen one in a nodule like that.

 

My other thought was some kind of arthropod exoskeleton

Crab was my first thought, so I agree with the above statement.

I'd say crab as well. Looks to be concave, which would mean we're looking at the inside of the carapace if that's the case.

I think there is more of the crab in the rock, and it would benefit from a professional preparation.

Nice find, especially for such a low price.

 

Maybe one of TFF's crab experts can identify where it came from.

I believe this is just a single crab claw a concretion.

This is not a claw, it's a raninid carapace.

This was the part that was throwing me off. That, and the heavily pitted texture.  I don't have one of these to reference and can't find anything on Google. Do these crabs have a line of spikes going down the sides of the carapace?

piranha hit this one right on the nail head.  If there is enouph rock underneath, it may have some leg and there could be claws, but usually, when I find these, they are moslty just the carapace.

Welcome to The Fossil Forum!  Ah...it's just an old, dead crab.  Have you ever smelled a dead crab that has been sitting around for a while?  They really STINK!  I think you need to sell it to me for $2 (double your money) and I'll even pay the shipping to Texas! :D  Just kidding, of course!

 

Nice find!  I'm going to have to start hitting estate sales more often!

Thanks to everyone for your response. It's nice to finally know what it is. Who says there is nothing to be found in the glaciated parts of Wisconsin :). Thanks again!

Wisconsin? You should find all kinds of fossils up that way. Definitely a crab shell. I found most of mine in PA and Ohio.
