Dyrosaurus was an extinct genus of dyrosaurid crocodyliform from the Eocene of North Africa. The type species D. phosphaticus possessed slender jaws with numerous recurved teeth, indicative of a primarily fish diet (similar to the extant gharial). Dyrosaurus teeth have smooth enamel and are long and often sharp, helping it to hunt fast-moving prey.
