Metoposaurus is an extinct genus of temnospondyl amphibian, known from the Late Triassic of Germany, Italy, Poland, and Portugal.[1] [2] This mostly aquatic animal possessed small, weak limbs, had sharp teeth and a large flat head.[3] The main diet of this highly flattened creature was fish which it captured with its wide jaws lined with needle teeth. Metoposaurus was up to 3 m (10 feet) long, weighed 454 kg (1,000 pounds),[4] and was one of the last large amphibians. Still, the much larger Koolasuchus survived far into the Cretaceous. A lot of Metoposaurus mass graves have been found, probably from creatures that grouped together in drying pools during drought.

In Popular Culture[edit]

Metoposaurus was shown in the "Dawn of the Dinos" episode of Paleoworld. It was also shown in a book version of Walking with Dinosaurs.
