Anthracosaurus is an amphibian in Additional Creatures.


Anthracosaurus is a large, elongated species of Amphibian found in several of the ark’s bodies of freshwater. A fish-eating predator, Anthracosaurus spends its time patrolling its murky home for food to eat-whether it be fish, small animals, or survivors. What’s noted for Anthracosaurus is however its long shape. This shape is very similar to an electric eel, and Anthracosaurus also has powerful electrical organs. It can use this passively in two ways. In one way, it can use its electrical properties to detect ElectroMagnetic Fields, allowing it to make sense of its murky environment. Second, it can also use its electricity to jolt any attacker that comes into physical contact with it! It has a third, much more active use as well: able to emit a powerful electric shock along its body’s length in order to deter attackers and electrocute them in place, so it can either fight easier or retreat. These electrical properties make Anthracosaurus a valued creature in any survivor’s arsenal.
