History of the Earth Part 2: Phanerozoic Eon – Paleozoic Era

The video explores the Paleozoic era, a time of significant change from 541 to 252 million years ago. It covers the evolution of life from oceans to land, highlighting the development of vascular plants, lungfish, and amphibians. The era saw major geological events, including the formation of the Appalachian Mountains through three orogenies. The Carboniferous Period, known for its vast coal deposits, played a crucial role in shaping Earth's climate and future industrialization. The video concludes with the assembly of the supercontinent Pangaea, marking the end of the Paleozoic era.
