PachyrhinosaurusThis dinosaur  has a very bony lump on it’s nose as well as neck frill.

The Pachyrhinosaurus was walking in North America 70 million years ago and was estimated to be 6 metres long.

Scientists and archaeologists   have not yet found out if this ceratopsian had horns or not. Did you know even a mighty Mapasaurus  couldn’t always win a battle against a Pachyrhinosaurus.

It is believed that this dinosaur might have sometimes had coloured plates to attract mates.
