In this activity, you will use relative dating to analyze the age of fossils. Review these images, and then answer the
following questions. Image 1 shows fossils embedded between layers of rocks. The images of organisms in the layers
represent the fossils discovered in these rock layers. Image 2 shows the evolution of present-day elephants from the
early Eocene era.
The snail in layer E of image 1 is a previously unidentified species. How can scientists determine the relative age of the
fossil?
