Summary

Some of the giant marine reptiles that ruled the seas during the age of dinosaurs were better built for surprise attacks, while their relatives were better suited to chasing prey through open water, according to a Rutgers-led study. These animals, known as mosasaurs, were a group of lizards adapted to life in the ocean. Researchers reconstructed the bodies of four kinds of mosasaurs from their fossil skeletons, then applied principles of physics to estimate how quickly each could surge forward with a single powerful sweep of its tail.
