This ancient ancestor of today's most feared ocean predator, the shark, would have hunted whales and been able to snap up a great white shark as a snack! In this book, readers get to dive into the world of a prehistoric ocean giant and find out how scientists have used fossils and studies of modern-day sharks to look back millions of years and piece together the story of Megalodon.
