| Outline of Final Research Achievements |
The degree of pneumatization of the Deinocheirus was beyond sauropods, which is the largest terrestrial animals in the life history. Since this pneumatization is present in a basal form of this group, it was established at the early stage, and this dinosaur group became gigantic by progress of pneumatization along with evolution. Also, the skull has features characterized as a wide beak, a deep lower jaw, and a long snout. They had a structure that made it possible to divide foraging and food. Furthermore, it is thought that gastroliths in the body had a high degree of circularity and had high physical digestive activity in the stomach. Long neural spines have a much more complicated morphology than other dinosaurs. It was considered that long nural spines had multiple functions and evolved by changing the weight of the function as necessary.
