Hadrosaur

Hadrosaurids or duck-billed dinosaurs were members of the family Hadrosauridae, and include ornithopods such as Edmontosaurus and Parasaurolophus. They were common herbivores in the Upper Cretaceous Period of what are now Asia, Europe and North America.

Paleontologist Paula Shaffer travelled back to Upper Cretaceous Montana to do a field-study on hadrosaurs. During her study, she imprinted on a new-born hadrosaur, and then found herself in a stampede as the herd fled from attacking gorgosaurs. While she and her infant hadrosaur were lost overnight, hadrosaur instinctively hatched in the same areas. Paula followed her infant back to the nest.
