Temnodontosaurus was a large marine reptile that lived during the Early Jurassic period, approximately 190 million years ago. As one of the largest ichthyosaurs, Temnodontosaurus could reach lengths of up to 12 meters (39 feet). It had a robust, streamlined body similar to that of modern dolphins, with a long, pointed snout filled with sharp, conical teeth designed for catching prey. Temnodontosaurus’s large eyes, which could measure up to 20 centimeters (8 inches) in diameter, were among the largest of any known animal, providing excellent vision for hunting in the dimly lit depths of the ocean. It primarily fed on fish and cephalopods, using its powerful jaws to capture and consume its prey. Fossil evidence suggests that Temnodontosaurus inhabited the shallow seas of what is now Europe. The discovery of numerous well-preserved fossils has provided significant insights into the diversity and adaptations of ichthyosaurs, highlighting their role as top predators in the marine ecosystems of the Early Jurassic.
