Hadrosaurus

Hadrosaurus was a 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 , which lived at the same time and place, or like that of later hadrosaurids, such as Edmontosaurus or Parasaurolophus.

Jurassic Park
Hadrosaurus is one of the dinosaurs that are cloned by InGen in the fist novel. The Hadrosaur herd in the park consisted of 11 individuals. They shared a paddock with Maiasaura, due to them being close relatives of Hadrosaurus, Apatosaurus, and Microceratops. No reproduction is observed among the Hadrosaurs. Both the Tyrannosaurus rex and the Velociraptors were able to reach their territory and take some down. One of the most dramatic scenes involved the Tyrannosaurus rex causing the Hadrosaurus herd to stampede, in which case it successfully hunted and killed one individual, while the rest of the herd nearly trampled Dr, Alan Grant and the Murphy children. In the film, this scene was ultimately replaced with a Gallimimus stampede. At the end of the novel, it is shown that only 5 Hadrosaurs are left. One is later killed by a pack of raptors, leaving only 4 Hadrosaurs left. The rest are later killed by the Costa Rica Napalm Bombing.

The Lost World
Hadrosaurus is never seen or mentioned in the sequel to Jurassic Park, The Lost World. However, they might have died out due to their lack to reproduce, or just nesting in a different region of Isla Sorna.

Return to Jurassic Park
A Hadrosaur is seen in the first issue of Return to Jurassic Park. It is seen as a dead body being devoured by a Tyrannosaurus. This is probably a reference to the novel where a Hadrosaurus was killed by the adult Tyrannosaurus rex.
