Did Cooling Oceans Trigger Ordovician Biodiversification? Evidence from Conodont Thermometry
A favorable climate regime implies not only that the oxygen isotopic composition of Ordovician seawater was similar to that of today, but also that climate played an overarching role in promoting the unprecedented increases in biodiversity that characterized this period.
Oxygen isotope fractionation between human phosphate and water revisited.
Asian monsoons in a late Eocene greenhouse world
Late Eocene climate records reveal marked monsoon-like patterns in rainfall and wind south and north of the Tibetan–Himalayan orogen, indicated by low oxygen isotope values with strong seasonality in gastropod shells and mammal teeth from Myanmar and by aeolian dust deposition in northwest China.
Thermal evolution of Cretaceous Tethyan marine waters inferred from oxygen isotope composition of fish tooth enamels
[1] The evolution of subtropical (30–35°N) upper ocean temperatures through the Cretaceous is inferred from the oxygen isotope compositions of 64 fish teeth (enamel) coming from the western Tethyan
Evidence for major environmental perturbation prior to and during the Toarcian (Early Jurassic) oceanic anoxic event from the Lusitanian Basin, Portugal
The timing and causal relationships between the pronounced negative C isotope excursion and paleoenvironmental perturbations associated with the Toarcian oceanic anoxic event (Early Jurassic) remain
