Saurolophinae is a subfamily of hadrosaurid dinosaurs. Members of the subfamily derive from the Late Cretaceous of Antarctica, Argentina, Canada (Alberta and Saskatchewan), China, Kazakhstan, Mexico, Russia, the United States (Alabama, Colorado, Georgia, Mississippi, Montana, New Jersey, New Mexico, North Carolina, North Dakota, South Dakota, and Wyoming) and Uzbekistan.

Classification

Taxonomy

The following taxonomy includes dinosaurs currently referred to the Saurolophinae and its tribes.

Kritosaurus restoration

Saurolophinae was first defined as a clade in a 2010 phylogenetic analysis by Prieto-Márquez.[2] Traditionally, the "crestless" branch of the family Hadrosauridae had been named Hadrosaurinae. However, the use of the term Hadrosaurinae was questioned in a comprehensive study of hadrosaurid relationships by Albert Prieto-Márquez in 2010. Prieto-Márquez noted that, though the name Hadrosaurinae had been used for the clade of mostly crestless hadrosaurids by nearly all previous studies, its type species, Hadrosaurus foulkii, has almost always been excluded from the clade that bears its name, in violation of the rules for naming animals set out by the ICZN. Prieto-Márquez (2010) defined Hadrosaurinae as only the lineage containing H. foulkii, and used the name Saurolophinae instead for the traditional grouping.[2]

The cladogram below follows Godefroit et al. (2012) analysis.[3]

The following cladogram was recovered in the 2012 phylogenetic analysis by Prieto-Márquez and Wagner (the relationships within Lambeosaurinae and between basal hadrosauroids aren't shown).[4]
