How can we use the law of super position to determine the relative age of a fossil?

• fossils that are found in lower sedimentary rock layers are older than fossils that are found in layers that are above those layers

• the law of superposition can not be used for determining the age of fossils

• fossils that are found in layers of sedimentary rocks are usually older than the rock layers they are found in

• fossils that are found in upper layers of sedimentary rocks are the oldest of all fossils
