酷東西

趣味知識

Olorotitan had a very long neck for a duck-billed dinosaur, with 18 neck bones. That is why its name means 'titanic swan'.1 2

Its hollow head crest was tall and helmet-shaped, made from expanded skull bones that held the nasal passages.1 2

The skeleton of Olorotitan is the most complete lambeosaurine (a type of duck-billed dinosaur) ever found outside North America.1 2

Olorotitan lived about 72 to 66 million years ago, during the Maastrichtian age of the Late Cretaceous.3

It was one of the last non-bird dinosaurs to go extinct, dying out in the great extinction event 66 million years ago.1

The tail of Olorotitan had extra connections between the bones in its upper part, which may have made that section stiff.2

Olorotitan is closely related to the North American dinosaurs Corythosaurus and Hypacrosaurus.2
