Full text linkThe oxygen isotopic composition of conodont apatite derived from the Late Triassic (Carnian to lower Norian), Pignola 2 and Sasso di Castalda sections in the Lagonegro Basin (Southern Apennines, Italy) was studied in order to constrain the habitat of Late Triassic conodont animals. Oxygen isotope ratios of conodonts range from 18.5 to 20.8‰ V−SMOW, which translate to palaeotemperatures ranging from 22 to 31°C, assuming a d18O of Triassic subtropical sea water of −0.12‰ V−SMOW. These warm temperatures, which are well comparable to those of modern subtropical−tropical oceans, along with the body features of the conodont animal suggest that conodont d18O values reflect surface water temperatures, that the studied conodont taxa lived in near−surface waters, and that d18O values of Late Triassic conodonts can be used for palaeoclimatic reconstructions
