The Age of Reptiles in Three Acts

The video explores the Mesozoic era, highlighting the rise and fall of reptiles, including dinosaurs, during the Triassic, Jurassic, and Cretaceous periods. It discusses the evolution of flora and fauna, the impact of mass extinctions, and the eventual dominance of mammals and birds. The Mesozoic era ended with the K-PG extinction, paving the way for the Cenozoic era.
