Fossils

Mosasaur Jaw Rocks hold secrets to Earth's past. Fossils, which are the preserved remains of life, provide tremendous amounts of information about Earth's history. The fossilization of organisms can occur in a few different ways. Scientists have discovered that if the recently deceased organism is buried quickly it will have a better chance of becoming a fossil. The study of fossils can provide insight to the type of climate, organisms, and conditions that existed at the time when the original organism lived. Even from a fossil like the Mosasaur jaw shown, scientists can infer clues about the life of an organism.
