Hyneria

Hyneria was a prehistoric predatory lobe-finned fish that lived during the Devonian period around 360 million years ago.

Etymology
Hyneria means "from Hyner", as the first Hyneria fossils were found near Hyner, Pennsylvania.

Description
Size estimates have placed the length of the animal anywhere from two or three meters[2] and four meters.[1] In life, Hyneria could have weighed as much as two tons.[1] It has been theorized that the fins of Hyneria were strong enough for the creature to haul itself onto land. It may have "beached itself" by using an air bladder meant to maintain buoyancy as primitive set of lungs.
