Fossil Formation and Types in the Natural World

The video introduces different types of fossils, which are remains of once-living organisms. It covers mineralization, where minerals replace the original material of an organism, and carbonization, where a carbon outline is left after compression. Molds and casts form impressions of organisms, while trace fossils capture evidence of behavior like footprints. Finally, original material can be preserved in ice or amber. The video concludes with a summary and encourages viewers to subscribe.
