Among the various types of hadrosaurs which lived in what is now North America during the Late Cretaceous period was the Parasaurolophus, which was distinguished by the long, tubular crest on its head. This assembly kit reproduces this well-known dinosaur and includes two types of heads to depict male and female dinosaurs. The set also includes three Nyctosaurus, one resting on a rock and two in flying poses, as well as a same-scale human figure for size comparison.
