The generic name Olorotitan means "titanic swan" because its neck is longer when compared with other hadrosaurs, while the specific descriptor arharensis refers to Arhara County where the fossil was found.[1]
Description
Olorotitan arharensis is based on the most complete lambeosaurine skeleton found outside North America to date. It was a large hadrosaurid, comparable with other large lambeosaurines such as Parasaurolophus cyrtocristatus,[1] and may have grown up to 12 metres (39 ft) in length, up to 3.5 metres (11 ft) in height and within the range of 2.6–3.4 metric tons (2.9–3.7 short tons) in body mass.[2][3]
