Metoposaurus

Metoposaurus meaning "front lizard" is a genus of Stereospondyli temnospondyl amphibian, known from the Late Triassic of Germany, Italy, Poland, and Portugal.[1][2] This mostly aquatic animal [3] possessed small, weak limbs, sharp teeth, and a large, flat head.[4] This highly flattened creature mainly fed on fish, which it captured with its wide jaws lined with needle-like teeth. Metoposaurus was up to 3 m (10 feet) long and weighed 454 kg (1,000 pounds),.[4] Many Metoposaurus mass graves have been found, probably from creatures that grouped together in drying pools during drought.
