Figures
With only a transient excursion in atmospheric CO2 (panelA, from ref. 7), global temperature (panelB, from ref. 8), and surface ocean pH (panelC, from ref. 7) during the onset of Deccan volcanism, and conditions returning to preevent values by the time of the Chicxulub impact, there is little evidence for Deccan outgassing contributing to the Cretaceous–Paleogene mass extinction. Even the high-latitude fossil record cited by ref. as showing gradual extinction has been shown by higher resolution sampling panelD, from ref. to be a product of the Signor–Lipps effect, and in fact, this high-latitude location shows no more evidence for gradual extinction than low latitude diversity data panelE, from refs. and . Note, absolute pH and pCO2 values plotted here differ from ref. , as calculations here use updated seawater equilibrium constants.
