Fossils: A Journey Through Earth's Past

The video tutorial explores fossils, their types, and significance in understanding Earth's history. It covers paleontology, fossil dating, and the role of index, trace, and microfossils in geological and climate studies. Fossil resin, subfossils, and chemical fossils are also discussed, highlighting their importance in tracing life and studying past climates.
