Explanation

Fossilization is the process of an animal or plant becoming preserved in a hard, petrified form. Fossilization often results in the impression of an organism being left in a rock. When a leaf or an animal skeleton becomes a fossil, that's fossilization. Fossils are the preserved remains of a prehistoric creature — fossilization takes a very long time, so if you see a fossil, you know it's at least 10,000 years old. Originally, fossil was defined as "anything that's dug up," from the Latin fossilis, "dug up." By the 18th century, both fossil and fossilization specifically referred to "the geological remains of a plant or animal."
