Deccan Traps – Deccan Plateau, India – about 60 million years ago
The Deccan Traps are a set of lava beds in the Deccan Plateau region of what is now India that cover an area of about 580,000 square miles (1.5 million square kilometers), or more than twice the area of Texas. The lava beds were laid down in a series of colossal volcanic eruptions that occurred between 63 million and 67 million years ago.
The timing of the eruptions roughly coincides with the disappearance of the dinosaurs, the so-called K-T mass extinction (the shorthand given to the Cretaceous-Tertiary extinction). Evidence for the volcanic extinction of the dinosaurs has mounted in recent years, though many scientists still support the idea that an asteroid impact did the dinosaurs in.
