76 Million Years Ago: The Last Day of the Dinosaurs 🦕

YouTube Description: 76 million years ago, the world of the dinosaurs was already dying — and it had nothing to do with the asteroid everyone remembers. Long before the Chicxulub impact darkened the skies, dinosaur diversity across North America was collapsing, sea levels were falling, and half a world away, the Deccan Traps were tearing open the Earth’s crust in one of the largest volcanic events in planetary history. This documentary reconstructs the true timeline of the dinosaur extinction — from the slow decline of the late Cretaceous period, through the catastrophic Chicxulub asteroid impact, to the extraordinary Tanis fossil site in North Dakota, where scientists found direct physical evidence of the actual last hours of the age of dinosaurs. Discover how paleontologist Walter Alvarez first uncovered the iridium layer that proved an asteroid strike ended the Mesozoic Era, how the K-Pg extinction event wiped out 75% of life on Earth, and why the dinosaurs’ true story is far stranger — and far more human — than the one we were taught in school. If you’re fascinated by paleontology, deep time, mass extinction events, and the history of life on Earth, this is the documentary for you. Topics covered: • The Cretaceous-Paleogene (K-Pg) extinction event • The Chicxulub asteroid impact and crater • The Deccan Traps volcanic eruptions • Dinosaur diversity decline before extinction • The Tanis fossil site discovery • Walter Alvarez and the iridium layer • How birds survived the mass extinction • The Western Interior Seaway and Late Cretaceous climate 🔔 Subscribe for more deep dives into Earth’s ancient history and the science of extinction. dinosaur extinction, K-Pg extinction event, Chicxulub asteroid impact, Deccan Traps, Tanis fossil site, last day of the dinosaurs, Cretaceous period, Walter Alvarez iridium layer, mass extinction event, paleontology documentary, prehistoric Earth, end of the dinosaurs, asteroid that killed the dinosaurs, dinosaur extinction theory, deep time documentary #DinosaurExtinction #Paleontology #Chicxulub #Cretaceous #EarthHistory #MassExtinction #DeepTime #NaturalHistory #ScienceDocumentary #Dinosaurs
