The more heavily armoured ankylosaurus will be most likely to win.

I think this is probably 50/50. Ankylosaurus has armor and a tail club, plus it's low to the ground and very hard to flip, but Triceratops is a good bit larger, more mobile, and very powerful, as well as having horns perfect for goring the ankylosaur. I could see it winning at times.

Ankylosaurus doesn't need weight to win against Triceratops, that club tail is gonna hurt a lot, and it is what will allow it to win.

Changed my mind here after this chart. Ankylosaurus wins, 6.5/10.
Skeletals are by GetAwayTrike, the specimens are the largest for both with AMNH 5040 (275 cm skull, >14 tonnes) and CMN 8880 (8 meters TL, ~8 tonnes).
