Eustenopteron concept art

Eusthenopteron is a large tetrapodomorph fish that lived 385 million years ago. Anatomically, it shows many features of tetrapods. Eusthenopteron can grow up to 1.8 meters long, about as long as a person is tall. It appears in Hell on Earth.

Initially, Eusthenopteron would be searching for food in the seas, escaping from Dunkleosteus and early sharks. When the extinction occurs, Eusthenopteron would be doing somewhat better than the giant placoderm, but that would not save it, as it goes extinct. Some Eusthenopteron (or perhaps a relative) might have evolved into Tiktaalik.
