Elaborate Headgear Found on New Dome-Headed Dinosaur Species.

A new species of pachycephalosaur, Platytholus clemensi, dating from around 68 million years ago, has been described by paleontologists Mark Goodwin of UC Berkeley and John “Jack” Horner of Chapman University. The skull likely had sported bristles of keratin, reminiscent of a brush cut, which may have been used for display or social and biological interactions involving visual communication. The skull also had a nasty gouge at the apex that had healed, indicating that a serious accident once befell the creature, but that it had survived long enough for new bone tissue to grow into the gash.
