To better understand what filled that space, researchers including a team from the University of Tokyo analyzed CT scans of fossilized Triceratops skulls. They compared those scans with the snout anatomy of living animals such as birds and crocodiles. By combining direct examination with informed reconstruction, they mapped out how nerves, blood vessels, and air...
