Chasmosaurus and other ceratopsians had  weak neck shields. The neck shield was used to make the ceratopsian appear bigger than it really was. If a predator bit the shield the ceratopsian would have suffered severe injuries. Largest head of any dinosaur was Torosaurus, whole head (including neck shield) was 2 meters long.
