Hadrosaurus

Hadrosaurus was the first Hadrosaur ever described, discovered in 1862 by Edward Drinker Cope in 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 hadrosaurs, such as Anatotitan or Parasaurolophus.

In Jurassic Park
Hadrosaurus is not seen in person in the Jurassic Park movie, or in the novels, but it is listed as being on Isla Nublar in the novels, and seen on a sign at the Jurassic Park ride.
