While on the hunt, great white sharks are known for their explosive bursts of speed. But some mosasaurs—marine reptiles that lived during the Late Cretaceous—may have been even faster. These ancient predators could lunge at prey at an estimated 15 miles per hour (24 km/h), potentially snatching their next meal in an instant. Now, researchers are finding that they were more efficient swimmers than previously thought, with evidence revealing more about their predatory behavior. https://on.natgeo.com/JWqUf6
