When an Asteroid Struck Earth 66-Million Years Ago: History of Dinosaurs - COAST TO COAST AM 2022

COAST TO COAST AM - 2022. American paleontologist Steve Brusatte, PhD, teaches at the University of Edinburgh in Scotland. The paleontology advisor on the ’Jurassic World’ film franchise, Brusatte discussed the history of dinosaurs and the rise of mammals in their wake. Mammals and dinosaurs both trace their ancestry back to the same place and time: when all land was joined together in the supercontinent Pangea, about 225 million years ago, he cited. Sixty-six million years ago, a six-mile-wide asteroid left a massive crater in Mexico’s Yucatan Peninsula. It struck with the force of over “one billion nuclear bombs,“ said Brusatte, and “unleashed a cocktail of wildfires, tsunamis, and earthquakes.“ The subsequent dust and grime went into the atmosphere and blocked out the sun, causing the Earth to grow dark and cold. The dinosaurs, who’d survived and thrived for millions of years, died out completely within a few thousand years. To learn more about featured guest speaker
