Evidence of Reduced Export Productivity Supporting Living or Heterogeneous Ocean Hypotheses for KT/K-Pg mass Extinction

Evidence for reduced export productivity following the Cretaceous/Paleogene mass extinctionAuthors:Esmeray-Senlet et alAbstract:The Cretaceous/Paleogene (K/Pg) mass extinction was associated with a collapse in the carbon isotopic (?13C) gradient between planktonic and benthic foraminifera and a decrease in bulk carbonate ?13C values.
