Stegosaurus was successfully recreated by InGen in the lab on Isla Sorna. The Stegosaurs were parented and fed in captivity on the island. Stegosaurus is green in color with brown plates exhibiting a paler center. InGen's Stegosaurus appears to be 12.192 meters (40 feet) long and 5.4864 meters (18 feet) tall at the top of the plates, which is much larger than Stegosaurus armatus, the largest known Stegosaur with a length of 10 meters (30 feet). InGen may have increased its size to make it more spectacular.
The Lost World: Jurassic ParkEdit
The Gatherers encountered a small Stegosaurus herd near a river bed; a pair bond, a subadult. and an infant.
Sarah Harding approached the herd very closely. She encounters an infant stegosaur, Claire, and she takes pictures of her. When the film of her camera was full it started to make noises. Because of the noise the herd sees Sarah as a threat to their young and start to attack Sarah.
Later, Peter Ludlow's hunters captured both an infant and an adult Stegosaurus. It is unknown if the baby Stegosaurus is Claire or an entirely different infant. They appear again near the end of the film migrating across the island.
Jurassic Park IIIEdit
Stegosaurs were also briefly encountered near another river where Dr. Alan Grant and the Kirby family road a boat through. Stegosaurs lined the river sides.
Masrani Global Corporation created a new dinosaur zoo on Isla Nublar: Jurassic World. These new clones had a dark tan skin with light olive green. The new clones appear to be the species, Stegosaurus armatus rather than a modified species like the originals. Stegosaurus lives in the Cretaceous Cruise, the Gentle Giants Petting Zoo and can be seen in the Gyrosphere attraction.
- The name "Stegasaurus" (A typo, obviously,) was seen next to a vial in the Cold Storage Room, when Dennis Nedry stole some embryos.
