Hyneria weighs two tons and is five meters long. She's an insatiable carnivore.
— Allen, about Hyneria

Hyneria ("From Hyner") is an extinct genus of lobe-finned fish from the Devonian period around 360 MYA.



Hyneria lived during the late Devonian Era 360-350 million years ago. It shared the waters with Dunkleosteus, Stethacanthus, and other sea animals and was one of the top predators of its time, second after the monstrous Dunkleosteus.


Measuring over 15 feet (4.5 meters) in length and weighing in at 2 tons (4,000 lbs.), Hyneria was a very large predatory fish. It had a solid bony skeleton, stout muscular fins and was covered in large scales. It also had powerful jaws and sharp teeth, and could swim fast, making it a deadly predator. It used keen eyesight and an acute sense of smell to detect prey, such as large fish and even primitive amphibians, such as Hynerpeton and Stethacanthus.


Hyneria was a solitary hunter, only getting together during mating season and living in lakes, rivers, and even the oceans, however, they were insatiable carnivores. Although a flesh-eating fish, Hyneria could attack their prey much like a killer whale would attack a seal, swimming up to the shoreline to catch their food. If they however missed their prey, they used their remarkably powerful fins to move on the land at least for a short time and take their prey by surprise.
