Click on "Play" in the Mission 2: Fossils Rocking the Earth
Introductory video: Fossils provide us with a historical record of life on Earth. There are many types of fossils, from extraordinary unaltered remains trapped in permafrost or amber, to subtle traces of past activities in the form of footprints and burrows. The fossils that we have found provide windows into the past and direct evidence of evolution. Before you start the first level in this mission, “Eating dinosaurs for dinner,” watch the introductory video and answer the next two questions.
