Fossils are most commonly found in sedimentary rocks, such as sandstone, limestone and shale. These rocks are formed as layers of sediment pile up over long periods of time. Plants and animals are preserved as fossils in the layers.

These extreme forces usually distort or completely destroy any remains trapped in the sediment. Therefore, scientists and palaeontologists rarely search for fossils in metamorphic rock formations.
