Join geophysicist Sonia M. Tikoo in this exploration of the end-Cretaceous extinction and the controversy around the definitive cause–asteroid impact vs. Deccan volcanism–for it. Learn how scientists study the aftermath of an asteroid crashing into Earth, and the path for the subsequent recovery of life at ground zero, after events of this magnitude.

This SciCafe is presented in collaboration with the International Ocean Discovery Program (IODP).
