“The Olorotitan, or "Gigantic Swan", was a duckbilled dinosaur from the Late Cretaceous period. According to Dr. Dua's notes anyway... Heh, a duckbill don't seem all that swan-like to me though.”
Olorotitan is a genus of hadrosaurid dinosaur that originated from Late Cretaceous Asia. A large, graceful herbivore, Olorotitan becomes available to Hammond Foundation operations upon completion of the Science Division's mission in the Muerta East facility.
Olorotitan was discovered in eastern Russia's Udurchukan Formation, and described by Pascal Godefroit in mid-2003. Its name means "titanic swan" for its neck, which is much longer than other hadrosaurs. It was related to the more well-known Lambeosaurus, as well as Corythosaurus, Tsintaosaurus, and Hypacrosaurus. Olorotitan is the most complete lambeosaurine hadrosaur found outside of North America and lived during later stages of the Cretaceous than many of its American relatives. During the Maastrichtian, lambeosaurine dinosaurs had become rare in North America but were thriving in Asia. Living alongside Olorotitan were Charonosaurus, which was very similar to Parasaurolophus and lived on the Chinese banks of the Amur river.
- Olorotitan was added with the Secrets of Dr. Wu DLC on November 20, 2018, along with Troodon, Ankylodocus, Stegoceratops, and Spinoraptor.
- Unlike its real-life counterpart, the game's Olorotitan has an upright posture when standing on two feet. In reality, it would've walked primarily on four legs, but when running on two, it would remain a horizontal posture.
- Despite the name, Olorotitan is not the largest hadrosaur. Edmontosaurus could potentially weigh 7 tons, while the gargantuan Shantungosaurus might have been the largest non-sauropod land animal of all time.
- Olorotitan is one of the few dinosaurs in the game with no prior depictions in the franchise's media.
