Saurolophini is a tribe of saurolophine hadrosaurid native to the Americas and Asia. It includes Saurolophus (from Canada and Mongolia), Augustynolophus (from the United States), and Prosaurolophus (from Alberta, Canada, and Montana, U.S.). Kerberosaurus and Kundurosaurus may also be members.[2] Bonapartesaurus, a hadrosaurid from Argentina, also has been identified as a member of this tribe.[3]

Fossils of saurolophins have been found in Canada, the United States and Asia, with the North American fossils being older than the Asian, suggesting saurolophins migrated intra-continentally.[1]
