Olorotitan, literally the "giant swan", was one of the very last dinosaurs to live in Asia before the mass extinction during the Late Cretaceous period. It was discovered in 2001 not far from the Amur, the river on the border between Russia and China. In common with the Parasaurolophus, the Olorotitan is a lambeosaurin, a hadrosaur that could make a tremendous noise with its hollow crest.
