Fantasia
Stegosaurus is one of many dinosaurs in the sequence, mixed in with 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 Tyrannosaur in an effort to save himself. However, he is killed and eaten by the Rex.

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

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.
