SE Texas - Equus tooth fragment?

[johnnyvaldez7.jv]

I found this tooth fragment today which I think might belong to Equus. I don't think it belongs to anything else... but I hadn't seen a horse tooth fragment where these lines were visible that run the length of it.  They probably are in each of them... I just hadn't seen it so wanted to confirm with those who know.  It's too busted for a chewing surface view. Almost no chewing surface available as it's kinda thin. Length is 2.3"

Looks like horse to me, but curious what the experts say.

I think horse is a possibility but it looks more like some of the fragments of mammoth enamel plate I've found.
