Hyneria
Hyneria is a genus of large prehistoric predatory lobe-finned fish which lived in freshwater during the Devonian period around 360 million years ago. Etymology. The genus name "Hyneria" is a reference to the village of Hyner, Pennsylvania, near where the first specimen was found. The species epiphet "H. lindae" is derived from the name of the wife of Keith Stewart Thomson, who described this fish. Description. "Hyneria" was a large fish, estimated at in total length. Its skull had heavy, ornamented dermal bones and its lower jaw was relatively long and shallow. The teeth were stout with those  of the premaxilla forming fangs upwards of . Its body was covered by cycloid scales. It had large sensory canals to aid in detection of possible prey, as the freshwater environment it inhabited likely was murky and had low visibility. Discovery. The original fossils came from two localities in Pennsylvania, United States, one found between the villages of North Bend and Hyner and another near Emporium. They consisted of a disarticulated partial skull and fragments of the shoulder girdle. The fossils were found in the Catskill Formation of the Red Hill Shale, dating to the upper Devonian. These were the only  remains known until 1993 when a renewed collecting effort discovered abundant new material. "Hyneria" is considered the largest and most common lobe-finned fish found in the Red Hill Shale.
