***Olorotitan*** is a genus of hadrosaurid dinosaur that originated from Late Cretaceous Asia. A large, graceful herbivore, *Olorotitan* is included in the *Secrets of Dr. Wu* DLC and becomes available to Hammond Foundation operations upon completion of the Science Division mission in the Muerta East facility.

## Characteristics

One of the largest hadrosaurs in the *Evolution* series, measuring up to 10 meters in length, *Olorotitan* is a large herbivore from the Late Cretaceous with distinctive duck-billed snout. Its name – its name translates to "*Gigantic Swan*", in reference to its long neck and striking fan-like crest on top of its head. While they are mostly bipedal, *Olorotitan* stand on all four limbs in a quadrupedal manner while feeding.

The base genome of the *Olorotitan* is light brown with creamy underbelly that turn into stripes that cover the tail. They have bright colored crests and additional orange stripes that go along the body.

### Behaviour

*Olorotitan* has a minimum herd requirement of three individuals and is unique in that it requires a population of four, either of fourth *Olorotitan* or another dinosaur. Due to their population tolerances, they make excellent additions to mixed herbivore exhibits. However, it is not advised to house them with most carnivorous species, as, like other hadrosaurs, they cannot defend themselves.

## Paleontology

In 2003, the first *Olorotitan* remains – a near-complete skeleton, in fact the most complete dinosaur specimen ever found in Russia – were discovered in the banks of the Amur River in Russia's Udurchukan Formation around the turn of the millennium. The same year, it was classified as a new genus by celebrated Belgian paleontologist Pascal Godefroit. Buried under a mudslide, the specimen was complete, and preserved well enough, that scientists were able to study the animal's brain structure. A carnivorous dinosaur's tooth was also found lodged in the Olorotitan's tail bones. Its name means "*Titanic Swan*" for its neck, which was much longer than those of other hadrosaurs. It was closely related to the more famous and well-known *Lambeosaurus*, as well as *Corythosaurus*, *Tsintaosaurus*, and *Hypacrosaurus*. The elaborate crest of the *Olorotitan* has helped paleontologists in reconstructing a more accurate crest for the *Tsintaosaurus*, which was initially believed to have a horn that resembles that of a narwhal.

*Olorotitan* is currently the most complete lambeosaurine hadrosaur found outside of North America and lived during later stages of the Cretaceous than many of its North American relatives. During the Maastrichtian stage, lambeosaurine hadrosaurs had become very rare in North America, but some like *Olorotitan*, were still thriving in Asia.

### Paleoecology

*Olorotitan* existed during the Late Cretaceous period, around 66 million years ago. The Udurchukan Formation and the overlying Yuliangze Formation on the Chinese bank of the Amur River were rich in hadrosaur fossils. The most complete after ***Olorotitan*** is *Charonosaurus*, which closely resembled *Parasaurolophus*. Other hadrosaur genera found here include *Kerberosaurus*, *Amurosaurus*, and *Kundurosaurus*. The main predator of this area was *Tarbosaurus*, a close relative of the infamous *Tyrannosaurus*. A variety of other dinosaur fossils have been found, including nodosaurs, dromaeosaurs, ornithomimids, and titanosaur sauropods. However, none are currently assigned to any genera. The climate of the region was warm and swampy, with a large variety of turtles, early mammals and crocodiles also being found here. Based on the proximity of known fossils to remains from turtles and crocodilians, *Olorotitan* probably lived in woodland and swamp areas.
