The story for kids
This is Pachycephalosaurus. Its name means "thick-headed lizard." On its head it had a round dome of bone, like a helmet, more than twenty centimeters thick! It walked on two legs and ate plants, fruit and seeds. Scientists think the males competed with each other by bumping heads, like rams do today. And now look: they're going to start!
