Is this bone, wood, or concretion?

Found this thing on a gravel bank...just thought it was unusual. My 1st thought was that it might be a small bone with river worn edges...seen it before with other bones found. But for it's size it seems too thick with the hole going all the way though. It has some bone like texture on the inside and outside. Then again those could be some natural made scratches from something or it's a piece of wood. Can't tell. Maybe someone has seen something similar. And it is completely mineralized.

Horn core ?

Interesting.  I just looked online for images.. this is pretty small...so do you thing it might just be the tip? Thank you for leading me in that direction...would've never occurred to me to think of that.

It seems likely. It's hard to imagine the horn of a juvenile mineralized that well.

Severely worn fragment of deer antler.

I've found several of these and agree with Harry.  It's a portion of an antler tine.
