Archelons are big, prehistoric turtles found only in the valley of Eodon. These turtles can be a danger due to their sheer size. However, they are easily distracted if offered some food, which takes less effort to acquire than hunting down their prey. Should they decide to have a snack anyway, they are surprisingly fast. Riding on the backs of these giant sea turtles was one method the Avatar's group could use to bypass a Tyrannosaurus in Savage Empire.
