For the past three decades Deccan volcanism has been suspected of playing a major role in the end-Cretaceous mass extinction but proof remained elusive due to the lack of marine microfossils for dating in this continental flood basalt province. Our study of KTB sequences between Deccan basalt flows in central and eastern India and oil company deep wells (3000-4000m) in the Krishna-Godavari Basin documented the mass extinction in planktic foraminifera in intertrappean sediments between the world’s longest lava flows near the end of the Maastrichtian and ending with the KT boundary. These studies directly link the mass extinction to Deccan volcanism (Keller et al., 2008, 2009, 2011, 2012; Adatte and Keller, 2013; Keller, 2014). An outcrop study in Meghalaya (NE India) documented the mass extinction 700 km from the Deccan volcanic Province (Gertsch et al., 2011).
