Hyneria lindae Temporal range: 360 Ma (Famennian) Scientific classification Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Sarcopterygii Subclass: Tetrapodomorpha Superorder: Osteolepiformes Family: Tristichopteridae Genus: Hyneria Type species: Hyneria lindae  Hyneria was a prehistoric predatory lobe-finned fish that lived during the Devonian period around 360 million years ago. Size estimates have placed the length of the animal anywhere from two or three meters and four meters. In life, Hyneria could have weighed as much as two tons. 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. n 1968, fossilized teeth, bones and a wall fin were found by Keith Thompson in the Red Hill Shale of Pennsylvania. Since the original discovery, many more specimens have been found. A complete skeleton, however, has never been recovered. Hyneria is considered the largest and most common lobe-finned fish found in the Red Hill Shale.
