Need a tooth id

[npquilm]

I posted these on North American artifacts to show off my finds today but not knowing what this tooth belongs to is killing me. Ice age bison perhaps? Found in a creek bed in Macoupin county Illinois. Thanks for the help!

Nice stem point and drill.... looks like a Bison tooth to me.
The part you have towards the bottom of the point is the chewing surface.

Scratch that... its horse.
