Disney Dinosaur (2000)[]
Role Pachyrhinosaurus are seen multiple times. They are one of the surviving herd of dinosaurs led mercilessly by the Iguanodon Kron.
Inaccuracies
- Pachyrhinosaurus are seen alongside Styracosaurus, despite living a few million years later.
- At the beginning, a Pachyrhinosaurus is killed by a Carnotaurus. Later, they are seen in a herd trying to get to a safe haven where they are safe from Carnotaurus. While abelisaurids were alive at the time of Pachyrhinosaurus, it is unlikely they would ever meet. Pachyrhinosaurus would have instead been preyed upon by tyrannosaurids such as Albertosaurus, Gorgosaurus and Nanuqsaurus.

Inaccuracies
- Pachyrhinosaurus is depicted with a short nasal horn, with its nasal boss supporting it. This is impossible, because studies of the boss' texture show more against this.
- Its also suggested by George Blasing that the horn was made of keratin, since no dinosaur had hair.
- It is showing galloping, although they likely ran similar to Rhinos in real life like all ceratopsians.

Walking with Dinosaurs: 3D Movie (2013)[]
Role A Pachyrhinosaurus named Patchi is featured in the Walking with Dinosaurs film of 2013 alongside his brother Scowler and his love interest Juniper as well as Alex the Alexornis. He gets a hole in his frill when a Troodon grabs him by the frill and tries to take him away as a meal, only to be stopped by Bulldust. Patchi later uses the hole in his frill to defeat the Gorgosaurus Gorgon. He does so by dislocating the arm of the Gorgosaurus, which causes him to roar in pain, and knocking out some of his teeth.
Inaccuracies Pachyrhinosaurus may have had quills on its back, but this is debated. The Walking with Dinosaurs Pachyrhinosaurus roar like all of the other dinosaurs in the movie, but real Pachyrhinosaurus would have trumpeted like swans and geese due to lacking a syrinx.

Trivia[]
- Pachyrhinosaurus was intended to appear in the film, but for whatever reason, likely because the model barely resembled Pachyrhinosaurus, it was renamed to Sinoceratops.
Amazing Dinoworld/Dinosaur Superworld (2019)[]
History and Design
Pachyrhinosaurus is dark green, with simple brown feathers on its back and sides.
Role
A herd of Pachyrhinosaurus is featured in the first episode, both in the winter and spring. In winter, they are shown wandering and digging for plants in the snow. The second time, the herd is by a river. A flock of Troodon keep them at bay so as not to trample their nesting grounds.
Inaccuracies
- The Pachyrhinosaurus model has a large elasmotherium-like nasal horn. All studies of the nasal region suggest it has a simple nasal boss.
- Pachyrhinosaurus is shown with filamentous structures identified by the narrator as feather-like fur as indicated by recent fossil finds. This is extremely inaccurate: no dinosaurs had fur like us mammals, and would be more accurate to say fur-like feathers, like that of an ostrich. Also, there is no known concrete evidence.
