Fossils can help us understand the long-distant past of our planet. Designed for educators and parents of middle and high school age youth, this packet includes 16 activities which range from hands-on simulations of making fossils to figuring out, from a fossil footprint, whether the dinosaur that made it was walking or running. Because similar fossils are found in various parts of the U.S. and Canada, the activities and explanations will be useful across North America.
