We Finally Solved Why Dinosaurs Went Extinct After a Century of Wrong Guesses

66 million years ago, an empire that had ruled Earth for over 165 million years ended in a single day. Not gradually. Not over thousands of years. In hours. And even stranger — science couldn't actually explain what happened until the 1980s. In this video, we tell the full story of the dinosaur extinction: from the bizarre theories scientists once believed, to the discovery of the asteroid, the scientific debate that still continues today, and a twist ending that will completely change how you see dinosaurs. Key takeaways from the video: Before the 1980s, there were over 100 different theories about why dinosaurs went extinct — some genuinely bizarre A Nobel Prize-winning physicist (not a geologist) helped crack the mystery by testing a rare element called iridium Unusually high iridium levels were found in the same rock layer worldwide, proving the event was global — evidence of an asteroid, not a local disaster The impact crater (Chicxulub) had actually been discovered years earlier during an oil survey, but no one realized its significance The impact released energy equivalent to a billion Hiroshima bombs, triggering earthquakes and tsunamis over a kilometer high Small and burrowing animals survived better than large ones due to lower food needs during the "impact winter" There's an ongoing scientific theory that volcanic activity in India (the Deccan Traps) also contributed to the extinction alongside the asteroid Birds are technically still dinosaurs, scientifically and taxonomically speaking If you enjoyed this video, don't forget to like and subscribe to the channel 🦖 #ancienthumans #dinosaur #survival #humanhistory #dinosaurs #dinosaurextinction #asteroidimpact #paleolithicage #ancientlife #lostknowledge #historymysteries #earthhistory #naturalhistory #historydocumentary #CuriousJourney
