Mesozoic Era Events and Impacts

The video explores the Phanerozoic Eon, focusing on the end of the Paleozoic Era with the Great Dying caused by volcanic activity in Siberia. It then transitions to the Mesozoic Era, highlighting the rise of dinosaurs and significant tectonic events like the breakup of Pangea. The era concludes with an asteroid impact leading to another mass extinction, paving the way for the Cenozoic Era and a mammal-dominated world.
