Mesosaurus (middle lizard) is an extinct genus of reptile from the Early Permian of southern Africa and South America. Mesosaurus was one of the first marine reptiles, and had many adaptations to a fully aquatic lifestyle. Shown here is an early reconstruction of the skeleton of M. brasiliensis showing many small teeth in the jaws (MacGregor, 1908).
