| Outline of Final Research Achievements |
This study focused on exploring the relationship between skeletal morphology and locomotor strategies among tetrapods.
In the first project, 3D-images of squamate skeleton were used to reconstruct the outlier of the body, and then the center of mass positions (COM) were estimated. After the method seemed valid for estimating the COM from the 3D skeletal morphology, the method was applied to estimate the COM of ornithischian dinosaurs, and their limb postures were re-considered.
In the next project, the strength of the coracoid bone against bending force and the flapping ability were compared among birds.
