An introduction to the different kinds of fossils in the form of dinosaur tracks. The kids will look at maps of trackways that were created by dinosaurs wandering around Utah millions of years ago in an area near St. George, now known as Johnson Farm. They will then make models of sea urchin shell imprints with plaster of Paris to understand how trackways are formed and preserved.
