For example, the element carbon has six protons, but can have six, seven, or eight neutrons. Using the principle of faunal succession, if an unidentified fossil is found in the same rock layer as an index fossil, the two species must have existed during the same period of time Figure 4. Rocks and structures are placed into chronological order, establishing the age of one thing as older or younger than another reversals magnetic reversals: In each element, the number of protons is constant while the number of neutrons and electrons can vary.
