GEOLOGY

Detailed explanation-1: -Mudstone, shale, and limestone are examples of sedimentary rock likely to contain fossils.

Detailed explanation-2: -Fossils are most commonly found in sedimentary rock among the three major rocks. Unlike most igneous and metamorphic rocks, sedimentary rocks form at temperatures and pressures that do not destroy fossil remains.

Detailed explanation-3: -Therefore, fossils are found in sedimentary rock, like sandstone, shale, limestone and coal. Igneous rock, like granite and basalt, is formed by molten rock erupting from deep within the earth. Metamorphic rock, such as marble, is formed by tremendous heat and pressure.

Detailed explanation-4: -Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions. Generally it is only sedimentary rocks that contain fossils.

Detailed explanation-5: -Since rapid burial in sediment is important for the formation of fossils, most fossils form in marine environments, where sediments are more likely to accumulate. Fossils come in many types.
