| Outline of Final Research Achievements |
There are significant intrashell variations in carbon and oxygen isotope composition (d13C and d18O, respectively) and trace element concentrations in modern brachiopod shells. This knowledge was applied to Carboniferous and Permian brachiopod shells collected from central Thailand, resulting in the establishement of a standard protocol to find shell portions, the original isotopic and chemical compositions of which were not affected by the vital effect and diagenetic alteration. Capitanian (Permian) seawater temperature estimated from the d18O values of such shell portions was 28-35 °C. This value is very similar to that in the equatorial region.
