Ordovician climate changes in the northern subtropics: The δ18O record from the Tunguska Basin, Siberia

Ordovician climate changes in the northern subtropics: The δ18O record from the Tunguska Basin, Siberia

Oxygen isotopes from bioapatite (conodonts) have been used for several decades to reconstruct the Palaeozoic climate history. During the Ordovician, conodont-based Î´18Ophos studies have revealed a general cooling trend throughout the system. The Î´18Ophos data from Estonia confirm this long-term sh...
