| Outline of Final Research Achievements |
This project aims to investigate the early radition of dinosaurs and effect of diet on it. We could not reconstruct diet of early dinosaurs as we have planned. On the otehr hand, from the body size distribution of nonplantigrade (digitigrade and unguligrade) dinosauromorphs and mammals, we pointed out that foot posture may have constrained their body size, caused absence of small sized species and directional evolutionary trend toward larger body size during their early radiation. We have suggested because dinosaurmorphs were the only nonplantigrade during the Mesozoic they could occupy mid to large body size in terrestrial tetrapod fauna at that time, like modern nonplantigrades.
