الموسم 1، الحلقة 11: Sixty five million years ago dinosaurs were wiped off the face of Earth. Over the years there have been a number of theories as to why, and for the last three decades it has been thought that the cause was an asteroid impact in Mexico. Now, some scientists believe that a giant volcano in India was the culprit, as well as other environmental factors. Either way, many agree that the demise of the dinosaurs could not have been a simple story of a single impact event, followed by complete extinction. It is believed by many that a complex interaction of events combined to fulfill a fate many thousands of years in the making.
