Using an exceptionally well-preserved fossil of the giant shark megadolon (Otodus megalodon), an international team of researchers created the first 3D model of megadolon’s body and used it to infer its movement and feeding ecology. Their results suggest that an adult megadolon could cruise at faster absolute speeds than any shark species today and fully consume prey up to 8 m (26 feet) long, the size of modern apex predators.
