This is an open species btw, you can design your own as long as you credit me. This is Bumper the Unicornium. Those are ancestors of modern day unicorns from the stone age. The were domesticated and came in standard size (the size of a white rihno) or pygmy (the size of a border collie). Of course they only had primitive magic, nothing like twilight sparkle would be capable. Just basic teleportation
