“Here we go, an 'enormous spine lizard', or Gigantspinosaurus. Not as large as its cousins, but with impressive shoulder spines, clearly for defense.”
Gigantspinosaurus is a genus of stegosaurian dinosaur that originated from Late Jurassic Asia. Gigantspinosaurus fossils can be discovered in the Ziliujing Formation in China, which unlocks for expedition teams on Isla Sorna.
Gigantspinosaurus is the last dinosaur found at the Ziliujing Formation and is harder to keep comfortable than Chungkingosaurus and Huayangosaurus. They require a minimum herd of at least four, or else they'll become quickly uncomfortable.
Gigantspinosaurus was an unusual stegosaur. Although it looked fairly similar to Kentrosaurus, it has characteristically huge shoulder spikes. These spikes would've been a formidable form of defence or used as a display feature for mates. The abundance of primitive stegosaurs such as Gigantspinosaurus and Huayangosaurus mixed with more advanced genera such as Chungkingosaurus and Tuojiangosaurus in the Dashanpu formation of China suggest the stegosauria evolved in Asia before migrating to Africa, Europe and North America.
