What Was Earth Like at Dinosaur Peak? | Cretaceous Hothouse World | Documentary For Sleep

One hundred million years ago, Earth was unrecognizable: continents splitting apart, oceans flooding deserts, atmosphere with 30% oxygen and 4× current CO₂, global temperatures 10°C warmer with no ice anywhere. This wasn’t dinosaur decline—this was their golden age. The Cretaceous lasted 80 million years (longer than the entire Age of Mammals), with peak diversity, largest land animals ever (Argentinosaurus 70+ tonnes), flowering plants transforming landscapes, and reptiles ruling land, sea, and air. T. rex, Triceratops, Spinosaurus, Quetzalcoatlus—all thriving until an asteroid ended 165 million years of dominance in a single day. This is the story of Earth during dinosaur supremacy, how climate and continents created conditions for giants, and why mammal dominance wasn’t inevitable—just lucky.
