What is "metoposaurus"

Metoposaurus (pronounced Me-top-o-sore-us) meaning "front lizard" is an extinct genus of Stereospondyli temnospondyl amphibian, known from the Late Triassic of Germany, Italy, Poland, and Portugal. This mostly aquatic animal possessed small, weak limbs, sharp teeth, and a large, flat head. 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),. Many Metoposaurus mass graves have been found, probably from creatures that grouped together in drying pools during drought.
