Battle scars reveal dinos were head bangers

[Still Waters]

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

The dinosaurs, known as pachycephalosaurs (meaning "thick-headed lizards") have long puzzled paleontologists, who wondered why the heads of these dinosaurs looked to have built-in football helmets.

It's been suspected that dome-headed dinosaurs fought with their heads, but the latest investigation provides some of the most direct evidence for this antagonistic behaviour.

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

Maybe there was a really good heavy metal group around then?

Nature never ceases to amaze me.

Yet, I wish I could have head-butted my ex a few times.

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...

They banged themselves smaller and smaller, till they are the little birds we see today.
