Authored by Pixtarsaurus

Pachyrhinosaurus, meaning "thick-nosed lizard", was a medium sized centrosaurine ceratopsian that lived in the Late Cretaceous Period of North America around 72-70 million years ago. It's most defining feature was its huge, bony mass, or lump, on its face. It was about 20 feet long and about 10 feet tall. It was closely related to Styracosaurus and more distantly related to Triceratops.
