History of the Earth Part 3: Phanerozoic Eon – Mesozoic Era

The video explores the Fanoryzoic Eon, focusing on the Great Dying, the largest mass extinction event caused by volcanic activity in Siberia. It then discusses the rise of dinosaurs in the Mesozoic Era, their evolution, and dominance over mammals. The video also covers significant tectonic events, such as the breakup of Pangea and the formation of the Atlantic Ocean. Finally, it examines the asteroid impact that ended the Mesozoic Era, leading to another mass extinction and paving the way for the Cenozoic Era.
