"That's not a real dinosaur."
Gray Mitchell(src)

Stegoceratops is a dinosaur hybrid of Stegosaurus, Triceratops, a beetle, and a snake, and will be identified by their horns. Their horns grow throughout their lives. Charging on hard material keeps the horns worn down and sharp. Other ceratopsian hybrids such as Sino-Spino and Pachyceratops are often mistaken for Stegoceratops. Despite appearing in the toy line and game adaptation of Jurassic World, it did not physically appear in the film itself.

Stegoceratops is seen on one of the computer monitors inside the Hammond Creation Lab, but it is unknown if it was ever created.[2]

Stegoceratops was originally supposed to physically appear in the Jurassic World film in a scene where Owen Grady and Claire Dearing encountered it in the jungle, discovering that Dr. Henry Wu was making more hybrids in secret, but it was cut when the script was being written, due to Colin Trevorrow's son saying that if they had Stegoceratops along with Indominus rex, the I. rex would feel less special.[3]

According to early designs of the hybrids shown on the Creation Lab's computer monitor in Jurassic World, the beetle used in its creation gives it "exo-skeletal [sic] armour". Furthermore, one of the renderings says "GENE ASSET ID OWL #092345.435" which suggests that the film version of Stegoceratops might have owl DNA, though since this was never used in the film, it is unknown if this is canon. It also two different code names; these being "STEG.235" and "STEGA.324A-1", but these were ultimately never used and the computer screen in the final film instead shows "TRX REX.345-ALPHA" like with Indominus rex and the Pachycephalosaur-theropod hybrid.[4]

It is similar to an animal from a movie called Yor, the Hunter from the Future, in which there is a creature that had identical traits like the hybrid. Coincidentally, it is also called Stegoceratops.

Despite it being part Triceratops, the face and horns resembles Nasutoceratops. Its frill appears to have been based on a hypothetical restoration of Triceratops by Nobu Tamura, although the frill on the Level 40 Stegoceratops from Jurassic World: The Game looks more like a Styracosaurus frill, not a Triceratops frill or a Nasutoceratops frill.
