Olorotitan life

Olorotitan (Swan Titan) is a genus of lambeosaurine hadrosaurid dinosaur that lived in the Udurchukan Formation of the Amur Oblast in Far East Russia, 72 – 66 million years ago, during the Maastrichtian Stage of the Late Cretaceous Period. Named for its swan-like neck, longer than those of other hadrosaurs (it has 18 neck vertebrae as opposed to the supposed maximum of 15 for hadrosaurs), Olorotitan is distinguished by its hatchet-shaped hollow crest, unique compared to the crests of its North American relatives. Otherwise, much like other hadrosaurs, Olorotitan possessed a battery of teeth to mash up food, while its crest, formed out of the bones containing the nasal passages, was also used as a striking display feature and as a means to amplify the animal's vocalizations. It was a large animal, 3.5 meters (11 feet) tall, 8 meters (26 feet) long, and weighed 2.6 – 3.4 metric tons (2.9 – 3.7 short tons). Olorotitan is depicted as being willing to risk a yearly journey through hazardous volcanic environments to take advantage of the area's geothermal heating, warm enough to properly incubate their eggs (which they lay and bury in elevated mounds), fertile enough to grow horsetails more nutritious than the best of grass.
