Fossils are physical evidence of organisms that lived in the distant past. They are typically formed when plants, animals, or other organisms are buried under sediment and subjected to pressure over time. The process of fossilization preserves the organism’s remains, which can include bones, shells, and even traces like footprints. Fossils are crucial for understanding the evolutionary history of life on Earth, providing evidence of species that are long extinct and helping scientists to reconstruct ancient environments.
