Hadrosaurus has traditionally served as the basis for a large subfamily called Hadrosaurinae, which was seen as a group of largely crestless group of hadrosaurs related to the crested subfamily Lambeosaurinae. However, the changing view of Hadrosaurus classification in relation to other hadrosaurs has led some scientists to rename these subfamilies. In a 2008 study, Hadrosaurus was found to be more primitive than either lambeosaurines or other “hadrosaurines”, and not a particularly close relative of classic “hadrosaurines” such as Edmontosaurus and Saurolophus. As a result of this, the name Hadrosaurinae was restricted to Hadrosaurus alone, and the subfamily comprising the traditional “hadrosaurines” was renamed the Saurolophinae.
