Horned dinosaur skull simulations suggest different fighting styles

Science News reports that researchers modeled six skulls from five horned dinosaur species and simulated the stresses of different combat moves. The results suggest Triceratops and Spiclypeus could withstand the forces of interlocking horns and wrestling, while Centrosaurus handled vertical jabs better than side-to-side forces. The early, hornless Psittacosaurus appeared poorly suited to combat.
