Battle scars reveal head-banger dinosaurs

Scientists have observed signs of violent head-butting on fossil skulls of pachycephalosaurs.

This particular species of dinosaur was unusual in that it featured an extremely thick skull that was so strong it would have been like having a helmet built in to its head. Scientists have long pondered over the purpose of such protection however it is generally believed that these dinosaurs would have fought one another by head-butting their rivals.

"Aggressive behavior is rampant in modern vertebrates, and birds and crocodiles are no exception," said researcher Joseph Peterson. "The head-slapping behaviour of crocodiles and the face-pecking observed in a variety of birds suggest that 'using your head' is not unique to pachycephalosaurs."

"Fossilised skulls of dome-headed dinosaurs retain signs of injuries from violent head butting or head shoving, say US scientists."

Doesn't surprise me since so many animals around today like to bang their heads over territory.

Alright! So those old Jurassic Park toys that had them lower their heads so you could slam them into each other (but usually smack your fingers) were actually correct! Shweet, wish I still owned them...

So, we finally have proof that pachycephalosaurs fought using their cranial domes! God bless the scientists who made the discovery!
