How Climate Change Helped Dinosaurs Take Over

The video explores the formation of Pangea and the early confinement of dinosaurs due to climate conditions. It highlights new research suggesting that climate, not physical barriers, restricted dinosaur movement. Fossil discoveries in Zimbabwe support this hypothesis. A climate model shows that dinosaurs began dispersing across Pangea after the Carney and Pluvial event. The video also covers the discovery of dinosaur tracks in Texas, revealing insights into dinosaur behavior and movement.
