Hyneria

Hyneria was a large carnivorous sarcopterigian that lived in the Late Devonian. It was first seen pursuing a Hynerpeton after swallowing a Stethacanthus whole, but the Hynerpeton clambered onto land, far from its reach. The next day, it assaulted a mating pair of Hynerpeton; they seem far away enough from this great beastly fish, but since it can breathe outside of water with primitive lungs, it hauls itself further inland, grabs the tail of a Hynerpeton, and proceeds to drown it, where the Hyneria shall feast offscreen. It should be noted that it probably could not crawl out of water in actuality, as it lacked weight-bearing wrists.
