Stegosaurus is a dinosaur that lived 150-145 million years ago during in the Late Jurassic Period. He is a character from Fantasia, appearing in the "Rite of Spring" segment.



Stegosaurus is one of many dinosaurs/animals in the sequence, mixed in with Permian, Triassic, Jurassic and Cretaceous species. When the Tyrannosaurus first appears, he is shocked like many of them. When the Tyrannosaurus lunges for the herbivores, the Stegosaurus is slow in getting away and fights the Tyrannosaurus in an effort to save himself. However, he is killed and eaten by the T-Rex.

Later, other stegosaurs appears in the group of dinosaurs marching through the drought. They are trapped in a muddy pit with Apatosaurus and Diplodocus then they are killed by heat exhaustion and attacked by desperately hungry Ceratosaurs.

The Little Mermaid (TV series)

A Stegosaurus also appears in The Little Mermaid episode "Land of the Dinosaurs" along with Apatosaurus, Triceratops, and Tyrannosaurus Rex.

Disney Parks

Stegosaurus appears in both the Primeval World diorama on the Disneyland Railroad and in the Universe of Energy at Epcot. In both attractions, his fight with the Tyrannosaurus is re-created.


  • Stegosaurus and Tyrannosaurus never coexisted, as they lived during different time periods spanning millions of years apart. Its main enemies were instead the Jurassic meat-eaters Allosaurus, Saurophaganax, Ceratosaurus, and Torvosaurus.
  • Stegosaurus has been found in both North America and Portugal; during the Jurassic, Portugal was a large island off the coast of North America, which allowed large dinosaurs to colonize it.
  • Stegosaurus has one of the smallest brains of any dinosaur proportionate to body size.
  • Stegosaurus' tail spikes measured more than a meter in length, and evidence exists that they were used for defense. Fatal wounds have been found in Allosaurus skeletons that fit the tail spikes of Stegosaurus. This indicates Stegosaurus' flexible tail was able to move the tail spikes quickly to defend itself from carnivores.
  • Despite their great size, Stegosaurus' back plates were actually quite delicate; they were thin, full of blood vessels and covered in keratin (found in nails and hair as well as claws and horns). At one time, they were assumed to be used for warming up or cooling the animal down. They were probably more for display and species recognition than heat regulation or defense.
