EVERYDAY SCIENCE

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

Detailed explanation-2: -Most fossils “hide out” in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock. Plants and animals that become sandwiched in this sediment eventually turn into fossils. Two examples of sedimentary rocks are sandstone and shale.

Detailed explanation-3: -Fossils are more common in some kinds of sedimentary rocks than others. There are many factors that can contribute to the likelihood of an organism being preserved as a fossil. Fossils are most common in limestones. That is because most limestones consist partly or mostly of the shells of organisms.

Detailed explanation-4: -Sedimentary rocks have the ability to retain fossils because unlike most igneous and metamorphic rocks, sedimentary rocks occurs at temperatures and pressure that do not obliterate fossil remnants. Therefore, fossils are found in sedimentary rocks.

Detailed explanation-5: -Fossils are formed in many different ways, but most are formed when a living organism (such as a plant or animal) dies and is quickly buried by sediment (such as mud, sand or volcanic ash).
