Definition: Rhadinophis is a genus of prehistoric mammals that lived during the late Miocene epoch, approximately 26 million years ago. These animals were characterized by their large, elongated bodies and had a distinctive long snout, which allowed them to hunt large prey such as fish or other aquatic animals. They are known for their ability to live in arid environments and had adaptations that made them better suited for desert life than those of their more terrestrial predators.
