The eotyrannos is a small, carnivorous amphibian native to the swamps of Thanatos.
The eotyrannus is a small amphibian, about 3 feet long. They resemble giant salamanders, but have an armoured skin to protect themselves from predators. They also have whisker-like appendages to sense the world around them.
Overall, the eotyrannos resembles a cross between a salamander and a copepod.
Like almost all chordates on Thanatos, the eotyrannos is a predator, feeding on omnishrimp, carrion and various crustaceans and insects.
