Hyneria was a prehistoric predatory lobe-finned fish that lived during the Devonian period around 360 million years ago. It was approximately 4 meters in length and weighed as much as two tons. There is evidence from bones that it had very strong fins and maybe could go onto land.
In 1968, fossilized teeth, bones and a tail fin were found by Keith Thompson in the Red Hill Shale of Pennsylvania. Many specimens have been found since then, although a complete skeleton has yet to be discovered. Hyneria was just one of many species of lobe-finned fish of the family Tristichopteridae, common in the Late Devonian period, along with its close relative Eusthenopteron, whose well-preserved fossils are common and so have been intensively studied by scientists for decades.
