The Cretaceous Period (As We Understand It) | Documentary for Sleep

Listen on Spotify: bit.ly/DinosaurHour The Cretaceous Period (As We Understand It) | Documentary for Sleep A long, slow walk through the entire Cretaceous Period, as our best modern science understands it. Drift from the early Cretaceous floodplains of the Isle of Wight (Iguanodon, Baryonyx, Polacanthus) to the giant rivers of North African Spinosaurus, across to the Patagonian giants Argentinosaurus and Giganotosaurus, into the dim Mongolian Gobi where Velociraptor and Protoceratops are preserved still locked in combat after seventy-five million years, and finally onto the late Cretaceous Hell Creek floodplain to walk beside a sleeping Triceratops matriarch while Tyrannosaurus rex hunts patiently through the ferns. Then, as the dawn approaches, the slow long ending: the asteroid, the impact winter, the small mammals who quietly inherit the world. Held lightly, honestly, with the uncertainty acknowledged where the rocks leave gaps. Follow Dinosaur Hour for a new long-form dinosaur sleep documentary every other day. Sources 1. Brusatte, S. L.
