  Perhaps the most unusual of the ceratopsians, or horned-faced dinosaurs, Pachyrhinosaurus did not have a nasal horn but instead had a thick, bony facial pad. Fossil evidence shows that the frills were highly individualized in size and shape and perhaps this was an indication of gender, family traits or other factors. Protection from predators was enhanced by herd behaviour – that, and the ability to run at up to 32 kilometres (20 miles per hour).
