GEOLOGY

Detailed explanation-1: -The dead plants and animals, where they are buried by more sediment results in the accumulation of minerals from water in bones which leads to formation of fossils. This makes sedimentary rocks the only rock type to contain fossils.

Detailed explanation-2: -Mudstone, shale, and limestone are examples of sedimentary rock likely to contain fossils. As the layers of sediment build up on top of one another, they create a physical timeline. The oldest layers, along with the organisms that were fossilized as they formed, are deepest.

Detailed explanation-3: -Among the three major types of rock, fossils are most commonly found in sedimentary rock. Unlike most igneous and metamorphic rocks, sedimentary rocks form at temperatures and pressures that do not destroy fossil remains.

Detailed explanation-4: -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.

Detailed explanation-5: -(Some coal deposits yield spectacular fossils; most do not.)
