The eruptions occurred over a 600–800,000 year time period between around 66.3 to 65.6 million years ago, spanning the Cretaceous–Paleogene boundary. While some authors have suggested that the eruptions were the primary cause of the Cretaceous–Paleogene mass extinction event, which dates to around 66.05 million years ago, this has been strongly disputed, with many authors suggesting that the Chicxulub impact was the primary cause of the extinction. While some scholars suggest that the eruptions may have been a contributing factor in the extinctions, others suggest that the role of the Deccan Traps in the extinction were negligible or even partially negated the effects of the impact.
