This program illustrates the different processes by which fossils are formed, what fossils tell us about the past, and how scientists interpret fossils. On location footage takes students to major fossil dig locations. Other terminology includes: mold, cast, imprint, petrification, index fossil, trace fossil, and paleontology.
