We Know Exactly When Dinosaurs Went Extinct

The video explores the asteroid impact that ended the Cretaceous period, causing mass extinction. Fossil evidence from Tanis, North Dakota, reveals the impact's timing in spring, affecting ecosystems severely. The study of fish bones and other fossils indicates the event's seasonal occurrence, providing insights into the extinction's dynamics. The impact's timing may have worsened the extinction in the Northern Hemisphere, while the Southern Hemisphere's dormant life forms might have fared better. Understanding these details helps interpret past disasters and anticipate future challenges.
