The Deccan Traps: The Other Suspect in the Dinosaur Murder Mystery
The Long Winter
4,632 views
A crack opened in western India and poured out lava for half a million years. It was still erupting long after the asteroid hit — and the argument over which of them killed the dinosaurs has run for four decades without being settled.
This documentary follows the Deccan Traps from the mantle plume that fed them to the last flows that came out three hundred thousand years after the extinction. Along the way: how sulphur dims a sky, why two laboratories dating the same Indian cliffs still disagree, what the boundary clay looks like under a microscope, and how quickly life came back afterwards. Three hours, quietly narrated, for a long night.
