This episode of Fossil Files, titled “Discovery of the Past,” explores the surprising story behind the discovery of dinosaurs. Instead of one single discoverer, the episode highlights three key figures: Mary Anning, who uncovered early prehistoric fossils; William Buckland, who scientifically described the first dinosaur, Megalosaurus; and Richard Owen, who later created the term “dinosaur.” Together, their discoveries helped shape our understanding of Earth’s ancient past and the creatures that once lived on it.
