Dakosaurus: The Dinosaur-Headed Marine Crocodile

Dakosaurus was a metriorhynchid, a type of fully marine reptile related to crocodilians. It consisted of two species, Dakosaurus maximus, who lived in Late Jurassic Europe, and Dakosaurus andiniensis, who lived in Late Jurassic and Early Cretaceous South America. Unlike the rest of the metriorhynchids and other prehistoric marine reptiles, Dakosaurus’s skull was short and deep, a shape vaguely resembling that of theropod dinosaurs. Despite their similarities, the closet ecological equivalent of Dakosaurus was not crocodilians or predatory dinosaurs but orcas, the killer whales.
