Hi, longtime lurker first time poster here.

 

I was wondering if you guys can help me ID this concretion my family found years ago near Calvert. I believe it might be a trace fossil of some kind, possibly a burrow or tunnel. I have found similar types at Westmoreland State Park. I can upload pictures from different angles if needed.

 

Any suggestions of what it could be?

Here is a pic of another angle, there is a second smaller hole.

bog iron pipe. some theorize that they start by encrusting tree roots and then grow from there.

  Nice specimen! There were nice ones found in the Cretaceous of NJ during road construction a while back. I want to say Rt34 but maybe a local NJ collector can confirm this.

Hmm Interesting,  I thought it might be simply a geological formation, but it's good to see that it might be one of those. I also have a sneaky suspicion that the ones on the lower left of this pic may also be traces of some type of root or burrows

My Nephew lives in north west Kansas, and say's they find the concretions while digging basements. Brings some each trip, home too my wife's brother so they have stacks of them around the yard. I have brought some home.   During my original search a lady replied that they find them in Florida. I have not found any other documentation about them. Hope this helps!
