Figure 23.1 represents a cross section of the seafloor through a mid-ocean rift valley, with alternating patches of black and white indicating seafloor with reversed magnetic polarities. At the arrow labeled I (the rift valley), the igneous rock of the seafloor is so young that it can be accurately dated using carbon-14 dating. At the arrow labeled III, however, the igneous rock is about 1 million years old, and potassium-40 dating is typically used to date such rocks. Note: The horizontal arrows indicate the direction of seafloor spreading, away from the rift valley. If a particular marine organism is fossilized in the sediments immediately overlying the igneous rock at the arrow labeled II, at which other location(s), labeled A—E, would a search be most likely to find more fossils of this organism?
