What Really Killed the Dinosaurs

The video explores the complex factors behind the extinction of dinosaurs, primarily focusing on the asteroid impact theory, known as the Alvarez hypothesis. It discusses the evidence supporting this theory, such as the Iridium layer and the Chicxulub crater. Additionally, it examines other contributing factors like volcanic activity from the Deccan Traps and marine regression. The video concludes by considering various scenarios and emphasizes the complexity of the extinction event.
