How do fossils form in sedimentary rock?
GeologyPaleontology
Quick Answer
An organism must be buried quickly enough to escape decay and scavenging. Over time, minerals replace or fill the remains, preserving shapes, shells, or bones.
The Full Story
Fossilization usually begins when dead plants or animals are buried by mud, sand, or volcanic ash. Rapid burial protects the remains from oxygen, bacteria, and animals that would otherwise destroy them. Minerals in groundwater can then permineralize the remains or leave an impression after the original material dissolves. Most fossils are found in sedimentary rocks because those rocks form in layers that can preserve buried life.
