==Discovery and naming== thumb|220px|left|upright|Fossils of the holotype specimen in situ The holotype specimen of Olorotitan, consisting of a nearly complete skeleton, was discovered in field work in the Udurchukan Formation of Kundur in the Amur region of Russia between 1999 and 2001. Pascal Godefroit and colleagues described and named it as a new species in 2003. It was the first nearly complete dinosaur specimen to be described from Russia, and is the most complete lambeosaurine skeleton discovered anywhere outside of western North America.
