Palaeoecology of Late Triassic Conodonts: Constraints from Oxygen Isotopes in Biogenic Apatite

  title={Palaeoecology of Late Triassic Conodonts: Constraints from Oxygen Isotopes in Biogenic Apatite},
  author={Manuel Rigo and Michael M. Joachimski},
The 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 &dgr;18O of Triassic subtropical sea water of -0.12‰ V-SMOW. These warm… 

Oxygen isotopic evidence for Late Triassic monsoonal upwelling in the northwestern Tethys

The oxygen isotopic composition of conodonts from the Pizzo Mondello section in the Sicani Basin (Sicily, Italy), on the northwestern Tethys margin, has been used to reconstruct regional

New Upper Triassic Conodont Biozonation of the Tethyan Realm

Conodonts are biostratigraphically very important microfossils in the Upper Triassic, occurring in different marine habitats, from deep-ocean to shallow-shelf waters. Because of their great

Oxygen isotope variability in conodonts: implications for reconstructing Palaeozoic palaeoclimates and palaeoceanography

Conodonts have the potential to elucidate the intricacies of Palaeozoic climates, especially if δ18O values of single apatitic tooth-like ‘elements’ can be used to map evolving sea surface

Constraints on Pennsylvanian glacioeustatic sea-level changes using oxygen isotopes of conodont apatite

Conodonts from U.S. Midcontinent cyclothems were studied for oxygen isotopes in order to constrain Pennsylvanian glacioeustatic sea-level fluctuations. Pennsylvanian deposits of the Midcontinent
