In popular culture[]

  • A herd of Ruyangosaurus are seen in Dino King 3D: Journey To Fire Mountain, where they first appear when their nesting grounds are raided by Carnotaurs, who steal their eggs, and when they break down a rock wall to help Speckles and Fang the Tarbosaurus and Cy the Saichania get through. Most viewers mistook them for Pukyongosaurus, despite from books relating to the movie calling them "Pukyongosaurus." However, an official poster for the movie officially claim them to be Ruyangosaurus.
