The Pachycephalosaurus' neck was not built for a forward headbutt, but when you consider a strike similar to giraffes, the skull's shape is ideal. The bony ridges and knobs at the back of the skull would deal no damage in a forward strike, but indeed be useful in side-strikes to the flank of an opposing dinosaur, likely of an entirely different species.
Contrary to popular belief, the Pachy actually better to knockout tames than the Equus. The Pachy induces more torpor per hit than the Equus and the Pachy also attacks over 15% faster. For added knowledge the Packy is also better than the Mantis (with bats), Pulmonoscorpius, and the Beelzebufo. As long as the Pachy is high level with melee damage pumped into it, it will beat any of the creatures I've mentioned with the same level and melee.
for everyoone saying they dont have a charge attack on mobile they do just go to settings and set right or left multi tap to reload/attack 2 then just tap the left or right side of the screen and ur pachy should start to charge thats also how u do barrel rolls on the pteranodon
The first time I heard one of these little critters, I thought, hey is that a goat?! Anyways, they are fun to have around and tamed, as they knock things out and run pretty fast while charging. However, they have considerably low health and stamina, so they can be quite troublesome when low lvl. But who cares, they make goat noises. If only they could eat anything
