I have to disagree with this one. If _Triceratops_ charged each other from a
distance, the results would be fatal to one or both animals. Think of jousting
knights using a spear (I forget the actual term), a shield, and that's it. No
body armor. Things are even worse for the other chasmosaurines, their frill is
not much of a shield, and is pretty vulnerable to damage (toss out the shield
in this one). Not a pretty picture.
I suggest that when these animals did fight, they did so at close quarters,
locking their horns and attepting to push their rival into submission (think of
deer for a moment).
Also, the semi-erect to fully sprawling posture that these animals had would
provide extra leverege and stability during these confrontations.
