The fossils found in the bottom layers of sedimentary rock are probably?

Animal remains are most likely to be fossilized if their hard parts are covered by layers of sediments soon after death. With time and pressure, these sediments, such as sand, plant debris, or ash, become compressed into rock. Therefore, fossils are found in sedimentary rock, like sandstone, shale, limestone and coal.
