NewzFossil evidence from more than 66 million years ago reveals that mosasaurs—marine reptiles related to modern lizards that inhabited the seas during the age of dinosaurs—possessed tails of distinct shapes. According to recent findings, the specific morphology of a mosasaur's tail allowed it to alter the distance between itself and its prey with a single strike, functioning as a key mechanism that made these animals lethal hunters in ancient marine environments.
The discovery highlights how anatomical variations in the tails of these prehistoric apex predators provided distinct hydrodynamic advantages. By examining the fossilized remains, researchers gained insight into the predatory mechanics of mosasaurs, demonstrating how subtle differences in tail shape directly influenced their hunting efficiency and success rate in the ancient oceans.
