Gilmoreosaurus was a medium-sized, duck-billed plant-eater from Asia. This dinosaur is an interesting example of how some discoveries are made not by digging through rock and dirt, but by looking in the basements of museums.

This dinosaur was originally found in 1923 by an expedition to Asia from the American Museum of Natural History. Ten years later it was named Mandschurosaurus and then mostly forgotten about. In 1979 Dr. Michael Brett-Surman, who is an author of the JP Institute Dinosaur Field Guide, studied the fossils and discovered that they had not been properly described. He found that this dinosaur had some very unique features and gave it its new name of Gilmoreosaurus.

This dinosaur also helps to establish a link between the Asian and North American hadrosaurs of the Late Cretaceous.
