ماستودونسور

Mastodonsaurus (meaning "teat tooth lizard") is an extinct genus of temnospondyl amphibian from the Middle Triassic of Europe. It belongs to a Triassic group of temnospondyls called Capitosauria, characterized by their large body size, large flattened skulls, and probably mainly aquatic lifestyles. Mastodonsaurus remains one of the largest amphibians known, and may have exceeded 6 meters (20 feet) in length.
