Hadrosaurus foulkii, the only species in this genus, is known from a single specimen consisting of much of the skeleton and parts of the skull. The specimen was collected in 1858 from the Woodbury Formation in New Jersey , US, representing the first dinosaur species known from more than isolated teeth to be identified in North America.
This clade excludes basal hadrosaurids such as Hadrosaurus and Yamatosaurus but self-destructs if Hadrosaurus is descended from the last common ancestor of Lambeosaurus and Saurolophus.

Hadrosauroidea was given a formal phylogenetic definition in the PhyloCode by Daniel Madzia and colleagues in 2021 as "the largest clade containing Hadrosaurus foulkii, but not Iguanodon bernissartensis". [1] The cladogram below follows an analysis by Andrew McDonald, 2012, and shows the position of Hadrosauroidea within Styracosterna: [2]

Parasaurolophus, a crested hadrosaur.. Hadrosaurids, also commonly referred to as duck-billed dinosaurs or hadrosaurs, were large terrestrial herbivores.The diet of hadrosaurid dinosaurs remains a subject of debate among paleontologists, especially regarding whether hadrosaurids were grazers who fed on vegetation close to the ground, or browsers who ate higher-growing leaves and twigs.
