Hadrosaurus

Hadrosaurus was a genus of Hadrosaurid dinosaurs that lived in the late Cretaceous Period. It was 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 hadrosaurids, such as Anatotitan or Parasaurolophus.
