Is this coprolite?

Found this in the creek behind my house in Eastern Kentucky. It's been raining (and flooding) a lot so tons of rocks are being washed out of the hills. I'm uncertain what era this could be from since I'm not exactly sure where it washed out from. 

 

The pictures I'm including show it while it was still in the rock and after I removed it. I thought it was made of metal at first, but it isn't magnetic at all, nor is it soft like lead or aluminum. After looking around online the closest thing I could find to it's shape is fish coprolite. 

 

Is this coprolite or just some strange thing in a rock?

Looks like a pyrite or limonite nodule.

Disappointing, but very informative. Thank you very much

I don't know if this stuff is found in Kentucky at all, but these look very similar to garnets in Schist which we have lots of around CT and the neighboring states

I looked that up and that looks very close to what i found here. After further research I found information on the University of Kentucky website that states we do in fact have those here. Thanks for helping me learn something new!
