Double whammy: Dinosaurs wiped out by one-two death punch delivered by colossal volcanic eruptions AND meteorite impacts

A single massive meteorite strike has always been considered responsible for wiping out the dinosaurs, but now scientists believe most of the creatures had already been killed by colossal eruptions from a volcano range three times bigger than France by the time it struck.

Researchers from Princeton University have found evidence that eruptions from the Deccan Traps, a primeval volcanic range in western India, devastated the Earth 65million years ago producing the largest lava flows in Earth’s history and filling the atmosphere with climate-altering carbon dioxide and sulphur dioxide.

As if this wasn’t bad enough, there were several more meteor strikes and, 300,000 years later, more eruptions that would ultimately make the Earth uninhabitable for 500,000 years.

Rock on: A massive meteor strike 65million years ago would have killed huge numbers of dinosaurs
