Bones can survive for thousands of years under the right conditions, and they can become fossils through a process called fossilization.
Key Concept
Fossilization
Explanation
Fossilization is a process that preserves organic remains over geological time periods. For bones to become fossils, they typically need to be buried quickly after the organism's death to protect them from scavengers and environmental conditions. Over time, the organic materials in the bones can be replaced with minerals, turning them into stone-like fossils. Factors such as the pH of the soil, temperature, and burial conditions can affect the preservation of bones. In some cases, bones can survive without fossilization if they are in extremely dry or cold environments that inhibit decomposition.
