| Outline of Final Research Achievements |
The habitat shifts from terrestrial to aquatic have been occurred in several lineages of tetrapods, accompanied by the shifts of the locomotor abilities of their forelimbs. However, both reliable life reconstructions of each extinct taxon and the timing of those shifts in locomotor strategies are yet to be understood. In this study, the thoracic strengths were estimated for various tetrapod taxa, including terrestrial and aquatic species. The analyses revealed that the thoracic strengths of the terrestrial and aquatic taxa were high and low, respectively. Therefore, the thoracic strength can be used as one of the useful tool to reliably reconstruct the locomotor abilities in the extinct tetrapod taxa.
