Dr. Robert Anemone, head of UNCG’s Department of Anthropology, appeared on a WFMY Kids Want 2 Know segment to answer a child’s question about why the dinosaurs died out. Numerous theories abound about dinosaur extinction. Anemone’s explanation? A large asteroid struck the earth about 65 million years ago, causing a climactic change in climate across the planet and wiping out major dino food sources.
