Ankylo VS triceratops

I'm almost certain that they both lived together at the same time, so if they happened to face each other, who would come out on top in a fight to the death?

Battle Information: A healthy adult Triceratops without injuries or diseases against a healthy adult Ankylosaurus without injuries or diseases. Both intend to kill the other, both are male if that makes a difference, the fight will take place in an open field with no other animals within a 60 km radius.
