I think it is a Heck Auruch, a german attempt circa Hitler. (Getting back to things old “German,” and all that.)
But, I’ve seen modern Aurochs that are the same size and even have the stripes down the back for males and red for females (as lives on in Jereseys).
Opinions differ, but domestic cattle as we know them are probably 3/4 middle eastern domestic 1/4 European auroch.
The current-day African cattle remain very similiar in pigment & horns to the European auruch(albeit thinner and attempted to drought/heat vs. cold).
The modern re-creation took African, Jersey, and Angus until they got back to auruchs.
Mean and big. I see why we killed them off.
I saw this bull at a livestock show in Louisville back in '80 or '81. I'm 5'11" tall, and this bull was as tall at the shoulder as I am. It was a big, big animal...
