| phylum | Chordata | Pachyrhinosaurus (meaning "thick-nosed lizard") is a genus of ceratopsid dinosaurs from the Late Cretaceous period of North America. Instead of horns, their skulls bore massive, flattened bosses; a large boss over the nose and a smaller one over the eyes. A prominent pair of horns grew from the frill and extended upwards.
