Fossils are formed through a process called fossilization, which typically occurs in sedimentary rocks. The process of fossilization begins when an organism dies and its remains are buried by sediment such as mud, sand, or ash. As the remains are buried, they may be subjected to pressure and heat, which can help to compress and mineralize the organic material, eventually turning it into a fossil.
Over time, the minerals in the surrounding sediment seep into the remains of the organism, replacing the organic material with hardened minerals. This process, known as permineralization, helps to preserve the structure of the organism’s bones, shells, or other hard parts. In some cases, other forms of fossilization, such as carbonization or impression fossils, may occur instead, depending on the conditions in which the organism is buried.
Once the fossilization process is complete, the fossil may remain buried for millions of years until natural forces, such as erosion or tectonic activity, bring it to the surface. Once exposed, fossils can be discovered by paleontologists and studied to learn more about the ancient organisms that once lived on Earth.
