Hadrosaurus was a genus of Hadrosaurid dinosaurs that lived in the late Cretaceous Period. It was described in 1858 by Joseph Leidy in Haddonfield, New Jersey. Its skull was never discovered, so its head shape is debatable, whether it looked like that of Kritosaurus, which lived at the same time and place, or like that of later hadrosaurids, such as Edmontosaurus or Parasaurolophus.

History[]

The Lost World: Jurassic Park[]

During the Isla Sorna Incident (1997), a info sheet of Hadrosaurus can be seen,[1] but no other information about this species is disclosed either in the InGen list or by the DPG,[2] so the state of possible activity of the species on any island is unknown.

Jurassic World[]

Hadrosaurus is seen on the Holoscape screen in the Innovation Center of Jurassic World,[3] and the Official Jurassic World Cookbook states that it resides along the Cretaceous cruise. However, as the Book is soft-canon at best and there is no further activity of Hadrosaurus confirmed on Masrani Global, IslaNublar.JurassicWorld.com, DPG or Dinotracker, the species’ existence remains as one of many mysteries in the franchise.

Trivia[]

Production and development[]

During the pre-production stage of the first film, Hadrosaurus was originally planned to be used in a scene that taken directly from the novel in which Alan Grant and the kids would observe the stampeding herd running away from the Tyrannosaurus, ultimately ending with the predator attacking and killing one of the hadrosaurs. Eventually, the film crew, specifically Steven Spielberg and Phil Tippett, decided to replace Hadrosaurus with the Gallimimus due to the fact that the latter could reach higher speeds.

In Scene 36 of The Lost World film script, Robert Burke mentions Hadrosaurus, along with Maiasaura and Corythosaurus (mislabeled Carinthosaurus), as one of the dinosaurs on Isla Sorna that the InGen Hunters are trying to capture.

Hadrosaurus was featured in concept art for Jurassic World: Fallen Kingdom. However, Colin Trevorrow confirmed there were no plans for it to be added to the final cut.
