Horse teeth- modern or earlier?

[Bonehunter]

So..............going  through my fossils I've had for decades, and just wanted to know if these two horse teeth are modern or "ice age" fossils. Both very heavy, creek finds in Kansas City and both have identical cusps. Thoughts appreciated!    Bone

Really?  Identical?  The larger tooth is an Equus sp. lower, right p3.  The smaller is unknown, perhaps a tridactyl horse.  If it were found in Florida, I would be asking about a Dinohippus lower, right m1.

Hey-thank you for clarifying!- I was just looking at the "pattern" of the cusp which looked reasonably similar, but looking again, I see the differences. This is fascinating!!!. Thank you so much....now I need to research Dinohippus/other equids.............so neither are "modern" eh?................. Bone

Equus is a genus that includes modern horses, dokeys, etc.
