Pachyrhinosaurus perotorum

Pachyrhinosaurus was a centrosaurine horned dinosaur from the Late Cretaceous of Alaska, although with a massive thickened bony boss over its snout and brow, it didn’t have as many horns as some of its relatives. Pachyrhinosaurus has been well-represented in dinosaur media projects, including being the star of the 2013 Walking with Dinosaurs movie, and key appearances in the documentaries Prehistoric Planet and Walking with Dinosaurs (2025).
