Brazos River, Texas - Tooth

[Mike Price]

I found this long tooth on the Brazos river. Any ideas of what it belongs too?

I think it looks more like a polished section of bone rather than a tooth.

I'm also not seeing a tooth but a bone.  Not seeing any enamel surface.  Having said that the last photo leaves me a bit puzzled.  It's concave like the base of something.  Great photos.
