What If An Asteroid Didn't Kill The Dinosaurs? (4K Documentary)

Synopsis

An asteroid impact 65 million years ago is widely recognized as a key factor in the mass extinction of dinosaurs, which dominated Earth for 150 million years. However, researchers are investigating additional elements that may have contributed to their decline. Studies of sediment cores and plant fossils from ocean floors reveal significant environmental changes, including a gradual decrease in oxygen levels. Scientists, including paleontologists from institutions like the Smithsonian National Museum of Natural History, are examining how these factors interacted with the asteroid event to shape the planet's ecosystems.
