Olorotitan was a magnificent ornithopod dinosaur that lived in what is now eastern Russia during the Late Cretaceous period, approximately 72 million years ago. This duck-billed dinosaur was one of the last non-avian dinosaurs to exist before the great extinction event that ended the age of dinosaurs. Its fossils were discovered near the Amur River in a region that was once a lush, subtropical environment filled with rivers and forests.
Standing about 4 metres tall at the hip and measuring 12 metres in length, Olorotitan was an impressive sight. Like other ornithopods of its kind, it possessed the characteristic duck-like bill that gave these dinosaurs their common name. However, Olorotitan was distinguished by its extraordinarily tall, hollow crest that extended backwards from its skull - one of the most elaborate head crests known among duck-billed dinosaurs.
As a herbivore, Olorotitan used its broad, flattened beak to crop vegetation and its batteries of grinding teeth to process tough plant material. It could move on both two and four legs, likely walking on all fours when feeding on low-growing plants and rearing up on its hind legs to reach higher vegetation or when moving quickly. The hollow crest served as a resonating chamber, allowing Olorotitan to produce deep, booming calls to communicate with other members of its species across the ancient Russian landscape.
Olorotitan possessed one of the most spectacular head crests of any duck-billed dinosaur, with a tall, backwards-curving hollow structure that was longer and more elaborate than those of its relatives. Its large size and distinctive crest shape made it unmistakable among the ornithopods of its time.
Olorotitan likely lived in herds and used its elaborate crest to produce loud, resonant calls for long-distance communication with other herd members. It could switch between walking on all fours when feeding and moving bipedally when traveling or fleeing from predators.
Olorotitan was first described by Pascal Godefroit in 2003. The original fossils were discovered at Udurchukan Formation, Amur Oblast, Eastern Russia.
