Were Dinosaur Brains Designed For Combat?

The thousands of Pachyrhinosaurus bones found at Pipestone Creek suggests that these animals lived together in herds. But did they always gather in such great numbers? To find out, scientists have taken X-rays of the skulls of these dinosaurs to see if their brain was suited to living in herds. The results shed light on this question and reveal how well adapted their skulls were for combat.
