Exploring Fossils and Plate Tectonics

David Whitman, a park ranger, introduces dinosaur bones and discusses their excavation history. He explains the ancient environment and climate, highlighting the role of continental drift and plate tectonics. Fossils and rocks are explored as clues to geological history, and the video concludes with an explanation of earthquakes and fault lines.
