Finding Fossils Along U.S. Freeways

Geologic pressures force ancient layers of rock above ground, exposing their cargo of fossils. Paleontologist Kirk Johnson and artist Ray Troll search the western United States for fossils and chronicle their finds in a new book, Cruisin' the Fossil Freeway.

Johnson and Troll speak with Andrea Seabrook.
