  Genus Pachyrhinosaurus
Pachyrhinosaurus was a herbivore (plant-eater) that lived in western North America during the late Cretaceous period, between about 72 and 68 million years ago. Its fossils have been found in Alberta, Canada, and in Alaska.

Pachyrhinosaurus was about 18 feet (5.5 meters) long, and weighed about 4 tons. Like other Ceratopsian dinosaurs, it had a massive head, a neck-frill, and spikes on its neck-frill. However, unlike some of its relatives it did not have a horn on its snout, but instead had a massive flattened bony lump ("boss"). Scientists believe that it probably used this boss in butting and shoving matches in a similar way to musk oxen do today.
