Fossil Meteorites and Earth's History

The video explores the discovery and significance of fossil meteorites, explaining how they form and how scientists identify them. It discusses the rarity of these meteorites and highlights the Thorsberg limestone quarry in Sweden as a key site for finding them. The video also examines the potential impact of meteorites on Earth's evolution, particularly during the Great Ordovician Biodiversification Event. Finally, it promotes Brilliant's educational platform.
