Detailed explanation-1: -Mudstone, shale, and limestone are examples of sedimentary rock likely to contain fossils.
Detailed explanation-2: -Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks. Sometimes the fossils have been removed, leaving moulds in the surrounding rock, or the moulds may have later been filled by other materials, forming casts of the original fossils.
Detailed explanation-3: -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-4: -(Some coal deposits yield spectacular fossils; most do not.)
