Texas - small tooth

[johnnyvaldez7.jv]

I found this little tooth...or at least part of a tooth and I can't figure it out. It's 1 cm wide...I'm assuming it's the chewing surface of a larger piece...but to what? Thanks for any help with this ID. SE Texas.

Looks like the heavily eroded top portion of a tooth from some sort of small artiodactyl - maybe deer?
