The Mastodonsaurus(Mass-toe-don-soar-uhs) (breast tooth lizard) is a large mastodonsaurid (temospondyl) amphibian that lived in the Middle-Triassic period in what is now Europe and Asia. These animals were huge predators, individuals have been found that grew up to 13-20 feet in length.
It is usually called the "Frog", but is sometimes called the "Newt", and "Kek" due to how it looks. It is small for its size. The Mastodonsaurus is a weak but fast amphibian in the game and is green with an orange underbelly. Because of this, most players prefer to travel between lakes and oceans with the Mastodonsaurus to find a safe place to live.
It's recommended to play out as a croc, grabbing your prey when it's drinking. You can also leave the water and grab a corpse to bring into the water. Mastodonsaurus falls on scavenger branches, go to Carnivore Branches for more information. Due to it being adapted for eating-swimming-disappearing.
It is light green in color, with a yellow underbelly and legs. It has white claws along with two long lower teeth that stick out of its snout of which looks like nostrils. It has two yellow eyes with black pupils sticking out of its head.
Mastodonsaurus was an abnormally large mastodonsaurid (temnospondyl) amphibian which lived in the Triassic period. In real life, the Mastodonsaurus was a medium sized three to four meters long temnospondyl amphibian, that lived like a crocodile, and attacked prey that got next to the water. It could not stay out of water for too long due to its skin and would die if it stood out of water too much. Weirdly, even though a Mastodonsaurus in real life would die on land after a certain amount of time, the in-game Mastodonsaurus doesn't have any Moistness.
