and Lambeosaurini (Corythosaurus, Hypacrosaurus, Lambeosaurus, others.). Corythosaurini (synonym of  Lambeosaurini, see below) and Parasaurolophini as terms entered the formal literature in Evans and Reisz's 2007 redescription of Lambeosaurus magnicristatus. Corythosaurini was defined as all taxa more closely related to Corythosaurus casuarius than to Parasaurolophus walkeri, and Parasaurolophini as all those taxa closer to P. walkeri than to C. casuarius.
and Lambeosaurini (Corythosaurus, Hypacrosaurus, Lambeosaurus, others). The terms Corythosaurini and Parasaurolophini were established in the formal literature by Evans and Reisz's 2007 reexamination of Lambeosaurus magnicristatus. These two groups are defined based on their phylogenetic relationships to Corythosaurus casuarius and Parasaurophus walkeri.
