| Description |
Artistic rendering of Pachyrhinosaurus perotorum engaged in head-butting/pushing behavior. In the first description of Pachryhinosaurus by Sternberg, he speculated that the enlarged nasal boss in the taxon might have been used in head battering or pushing behavior, an idea emphasized by this image of two Pachyrhinosaurus perotorum sparring with their craniofacial bosses, while a third looks on. |
