Just use a Bison. Or, for a very powerful bull, use a reskinned Rhinoceros. After all, it says right in the description that you can use these stats to model large herbivores with a gore attack.
Thanks for the links. Statistically, a Tauric human/bison has the same RHD, one extra feat, one extra skill point, and 10 extra feet of movement, but 1 less natural armor. Seems that the Tauric minotaur is better than the original Minotaur.
I'm impressed the stats are that close! I always felt the Tauric Creature lets you build rather powerful stuff for the CR, but it seems it's doing just fine at THE benchmark test.
