Any idea what this is?

I moved this request from Metal Detecting over to What Is It? for more exposure.

Size of a acorn or a truck differential?

Covan, we need much more info if anyone is even going to take a WAG
at what this might be.

How large is it (take pic next to ruler or common object). Is it a hard stone?

Seen something that looked like it before, but that was a turd from a black bear that had
been eating pinion pine nuts...

Maybe a rusted bearing that has an encrustation on it you need to clean it up some for a better ID.

need more info - details
looks like it could be a gear, drive bearing
the slots are a bit confusing, indicating they may drive something

The comcensus seems to be that it's an old wagon wheel hub from mid 1800's or from a Civil WR cannon wheel. Now to figure out how to clean it up.
