Pachyrhinosaurus (meaning "thick-nosed lizard") is a genus of ceratopsids from the Late Cretaceous of North America. Unlike more famous horned dinosaurs like Triceratops and Styracosaurus, it had a nasal boss. They appeared in March of the dinosaurs as a companion. However one fatally injured an Edmontosaurus in a fight just to get at some plants. A straggling female joined Scar and his companion during a migration but was left behind. Fortunately she caught up with scar and scared a starving Quetzalcoatlus. The next morning the entire herd crossed a river where many were eaten by mosasaurs. Pachyrhinosaurus also appears in Walking with Dinosaurs: The 3D Movie as the main protagonist along with an Alexornis.
