Dinopocalypse Redux

Using high-powered ballistics experiments, fancy computer algorithms, and good old-fashioned ancient geology, scientists have woven together a theory about the extinction of the dinosaurs that is so precise, so hot, so instantaneous, as to seem unimaginable. Today, we bring you this story, first published on Radiolab in 2013, plus an update: a spot on planet Earth, newly discovered, that - if it holds true - has the potential to tell us about the first three hours after the dinos died.

This update was reported by Molly Webster and was produced with help from Audrey Quinn. 

We teamed up with some amazing collaborators for Apocalyptical, the Radiolab live show that this episode is based on. Find out more about these wildly talented folks: comedians Reggie Watts, Patton Oswalt, Simon Amstell, Ophira Eisenberg and Kurt Braunohler; musicians On Fillmore and Noveller, and Erth Visual & Physical Inc.
