Here's a comparison
Eh, yeah I can kinda see it. Xenoceratops looks to me more like a shorter-horned Diabloceratops
The ARK Triceratops looks like it was modeled after Styracosaurus a little bit tbh. just more horns.
This is what happens when you apply what I call "awesomebroism" to herbivorous dinosaurs.
What do you think?
