Edmontosaurini is a tribe of saurolophine hadrosaurids that includes Edmontosaurus and its closest relatives. As Edmontosaurus has had a very long and complicated history with many now-dubious or invalid genera and species, the members of Edmontosaurini (and even its own validity) are questionable (the majority of the now-dubious or invalid species are not listed here). As hadrosaurs, all edmontosaurins are Grass Dinosaurs.
