The old view of the Pachycephalosaurus was that the dome on its head was for head butting duels between males , just like like stags at rutting season.
However this Has been proven not true as unlike stags which have reinforced skulls to take an impact, the rest of the the Pachycephalosaurus under the thick top bone plate cavity walls are particularly weak. Perhaps it was for sound as many scholars believe or maybe some lost feature like radar not present in modern day examples of the diversity of animal life. This is another example of your wildest guess, may actually be true!

This didn't happen!^^

I personally don't agree with the traditional skinny neck diagrams as described in 85% of illustrations and encyclopedias... it seams the creature would have a much saggier cowl like heavy neck, much more like a bulldog, or at least a whole new look. After all, deadly or not those spikes on its head must be awfully heavy to support.
Something is Definitely wrong with the current skin layer of Pachycephalosaurus i'm sure most of us can agree on that.


Dracorex hogwartsia (named after harry potters school Hogwarts as it resembled a dragon, when found in 2006)

Pachycephalosaurus were at one time three different dinosaurs. They are now thought to be different ages of the same dinosaur

Meaning thick headed lizard, a bipedal omnivore with an extremely thick skull roof. It possessed long hindlimbs and small forelimbs. Pachycephalosaurus is the largest known pachycephalosaur. Pachycephalosaurus is famous for having a large, bony dome atop its skull, up to 25 cm 10 in thick, which safely cushioned its tiny brain. The dome's rear aspect was edged with bony knobs and short bony spikes projected upwards from the snout. The spikes were probably blunt, not sharp
